Edition Features
Virtual Weather Station allows you to calibrate for
improved accuracy. In addition, if your wind speed sensor
is below the expected reading due to bearing life, or the
anemometer is obstructed by trees, these errors can be
adjusted to provide realistic values.
The Assistant
Menu Shortcut: Help u Assistant
The calibration takes the form of the following equation:
If you are a new user, it is advisable that you completely
run through the assistant to understand all of the features of
Virtual Weather Station.
Calibrated Value = Gain x Measured Value + Offset
When launching Virtual Weather Station for the first time,
the Assistant will automatically be displayed.
Reference Table 2 - Examples of Calibration. The table
provides solutions for typical measurement problems.
NOTE - changing the calibration settings in Virtual
Weather Station will not adjust the parameters displayed
from the console.
Note – setting the gain to 0 will cause the value to always
read 0. Only set the gain to 0 if you do not have the sensor
in your system.

Longitude and Latitude
To calculate the sunrise, sunset, moonrise and moonset for
your location, the longitude, latitude, and time zone is
required. If the sunrise and sunset appear incorrect, see
Troubleshooting Tips.
There are several sources for determining the longitude and
latitude for your location. The best source is the Internet.
Another source may be your local town hall.
GeoCode.com provides this information at the following
link:
http://www.geocode.com/modules.php?name=TestDrive_E

or browse to www.GeoCode.com and select the link “Test
Drive”.
Air Data Calculator (correcting Pressure
to Sea-level Conditions)
To compare pressure conditions from one location to
another, meteorologists correct pressure to sea-level
conditions. Because the air pressure decreases as you rise in
altitude, the sea-level corrected pressure (the pressure your
location would be at if located at sea-level) is generally
higher than your measured pressure. Thus, your pressure
may read 28.62 inHg (969 mb) at an altitude of 1000 feet
(305 m), but the corrected pressure is 30.00 inHg (1016
mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb).
Pressure conditions greater than 29.92 inHg (1013 mb) are
considered high pressure and less than are considered low
pressure.
Most weather stations instruct you to find a reporting
station near your location to identify the corrected pressure,
but Virtual Weather Station calculates this offset for you.
To calculate this offset:
Note – if you live in the Southern Hemisphere, enter a
negative sign in front of the latitude. If you live in the
Western Hemisphere (America, etc), enter a negative sign
in front of the longitude.

Virtual Weather Station displays your bias with

Wind Run
Wind run is the distance wind has traveled. For example,
the wind run for a constant wind speed of 20 mph for 2
hours is 40 miles, or:
Wind Run = Wind Speed * Time
There may be wind run calculation problems with specific
computers due to the microprocessor and other hardware
devices. If you find the wind run values are out of range,
place the following line in your win.ini file:
wuseDefaultTimer=True
To reset these values, select Settings | Recall Daily,

Your station may not calculate the pressure trend. Virtual
Weather Station will calculate the pressure trend based on

falling pressure.

Wind Gust Calculation
Each weather station uses a different method for calculating
wind gust. You can override your station’s default method
and select the maximum within a specified number of
samples.
Degree Days Heating and Cooling
Because temperature plays an important part in the rate of
development of plants and many pests, a measurement
which takes into account the accumulation of heat with
passing time is important to predict maturation. Degreedays provide a measure for calculating the effects of
temperature on the development of plants or pests.
6.16.5
Filtered Average Time Constant
The time constant for the filtered average can be varied.
The filter is based on a low pass filter differential equation.
The output value reaches 63% of the input value after one
time constant (the default time constant is 60 minutes or
one hour), and will reach 95% of the input value after five
time constants (default = 300 minutes or five hours).
One degree-day is the amount of heat which accumulates
when the temperature remains one degree above the
threshold for one day. One degree day is also the amount
of heat which accumulates when the temperature is 24
degrees above the threshold for one hour.
6.16.6
New Wind Chill Calculation
On November 1, 2001, the National Weather Service
(NWS) implemented a replacement Wind Chill
Temperature (WCT) index for the 2001/2002 winter
-27-
03/07/06
Virtual Weather Station User's Guide
season. The reason for the change was to improve upon the
current WCT Index used by the NWS and the
Meteorological Services of Canada (MSC, the Canadian
equivalent of the NWS), which was based on the 1945
Siple and Passel Index.
The new formula made use of advances in science,
technology, and computer modeling to provide a more
accurate, understandable, and useful for calculating the
dangers from winter winds and freezing temperatures. In
addition, clinical trials have been conducted and the results
of those trials have been used to verify and improve the
accuracy of the new formula.
Standardization of the WCT Index among the
meteorological community is important, so that an accurate
and consistent measure is provided and public safety is
ensured. Our goal was to implement the new wind chill
formula in Canada and the United States during the same
time frame in order to have a consistent WCT Index for
North America.
Specifically, the new WCT index will:

use calculated wind speed at an average height of
five feet (typical height of an adult human face)
based on readings from the national standard
height of 33 feet (typical height of an
anemometer);
ü
be based on a human face model;
In the event the daily and monthly rain is not calculated by
the weather station, the daily rain is calculated by
subtracting the minimum daily rain from the maximum
daily rain. To change the daily, monthly or yearly rain, you
must calculate the difference between the daily maximum
and minimum rain, and enter it in the minimum rain field.
ü
incorporate modern heat transfer theory (heat loss
from the body to its surroundings, during cold
and breezy/windy days);
The daily rain is stored by Virtual Weather Station as the
difference between the maximum daily rain and the
minimum daily rain, or:
ü
lower the calm wind threshold to 3 mph;
Daily Rain = Maximum Daily Rain - Minimum Daily Rain
ü
use a consistent standard for skin tissue
resistance; and
The same is true for monthly and yearly rain.
ü
assume no impact from the sun (i.e. clear night
sky).
Note that changing the daily rain does not change the
monthly or yearly rain automatically. You must edit the
monthly and yearly rain fields as well.
Virtual Weather Station allows you to use the old or new
wind chill models. For more information, please reference
the National Weather Service:
Some stations are not capable of reporting daily rain, so
Virtual Weather Station must be operating 24-hours per day
to capture the total amount.

Use Channel 1 As Outdoor Temperature
Some weather stations (example, Texas Weather

Virtual Weather Station’s WeatherVoice is a text to speech
converter. WeatherVoice is compatible with most text -tospeech voices.
These text files can be automatically updated, inserting
real-time weather conditions from your weather station, or
even forecasts and warnings from the National Weather
Service.
With WeatherVoice, you can:
Use Virtual Weather Station’s File Tags to insert live
weather conditions from your weather station or your local
METAR station into your outgoing answering message
Download from the Internet and insert any text file into the

7.1.3
Csv File
ü
Report Format. Provides formatted data for

A csv file (comma separated file) is a standard format for
reading data into Excel (for example). Excel recognizes csv
format and parses the data into separate columns.
ü
Comma Separated Data (csv) format. This format
is for export to Microsoft Excel or other analysis
programs.
To create a csv file, select the checkbox as shown in Figure
39 - File Settings.
ü
Archive Format. This format provides the highs,
lows and average for the day, month and year.
The data is stored in the following location:
\VWS\data\csv\yyyymmdd.csv
7.1.1
Daily File
where yyyy is the year, mm is the month and dd is the day.
The Daily File is a text file stored in the following location:
\VWS\data\daily\daily.txt
\VWS\data\csv\20000509.csv
This file is recreated every day. The file is formatted with
data organized into fixed column widths. This format is
ideal for display purposes.
7.1.4
Archive File
The archive text files consist of highs, lows and averages
for archived data on a daily, monthly and yearly basis. An
example of this file is shown in Figure 37 – Archived Data
Text File.
Since the file name never changes (daily.txt), it can be
statically linked from web pages or other files.

Creating Web Pages with Virtual Weather
Station Tags
NOTE: It is highly recommended you start with the html
templates provided with Virtual Weather Station and edit
these files to familiarize yourself with this feature. Run the
Weather Website Builder provided under the help menu,
and then explore the file templates and HTML files
generated from the templates.
8.13.1
Table 13– Other Jpg Filenames
8.11
Web Page Templates
Description of HTML Tags
HTML Tags allow you to insert weather station data text
into your web page. Virtual Weather Station accomplishes
this by searching for a known “Tag” in a “Template” file,
replacing the tag with weather data, and copying the
template to an HTML file. The steps are provided in the
following sections.
Intranet and Local Area Network
Applications
If your computer is on a Local Area Network or an
Intranet, both the ftp and web server options will work.
Virtual Weather Station provides another method, which is
direct jpg file transfer. This does not require use of ftp or
web server technology. Select the Jpeg Direct File Transfer
option. The files will be transferred to the Jpeg file location
specified in the panel.

8.13.2
Creating an HTML Template File (htx file)
HTX files or HTML template files can be created with
most Web Page authoring tools. Microsoft Frontpage is one
of several commercially available web authoring packages,
and there are several shareware software packages
available.
03/07/06
Virtual Weather Station User's Guide
To create a template file, save the template with an htx file
extension with any text editor or web authoring tool.

Menu Shortcut: Internet u HTML Tags
To view the complete list of tags, select the Complete Tag
List icon located in this window.
8.13.4
Inserting HTML Tags Into the Templates
There are three types of File Tags:
Each weather parameter has a unique file tag. For example,
the file tag for the outdoor temperature can be inserted into
your web page template as follows:
Figure 46 - HTML Tags
The following table provides an index of tag names:
Tag Name
Description
Outside Temperature: ^vxv006^^uni006^
WEATHER STATION DATA
yields, for example:
^vxv###^
Outside Temperature: 72°F
where the vxv006 is the HTML tag for outdoor
temperature, uni006 in the units of measure, and ^ is the
parsing character.
vxv = Virtual Weather value, ###
designates weather parameter number.
Example: ^vxv006^
METAR data that you download has a unique file tag. For
example:
^vhi###^
vhi = Virtual Weather Daily High
^vht###^
vht = Virtual Weather Daily High
Time
^vlo###^
vlo = Virtual Weather Daily Low
^vlt###^
vlt = Virtual Weather Daily Low Time
^vva###^
vva = Virtual Weather Running
(filtered) Average Value
^vda###^
vda = Virtual Weather Daily Average
Value
^vma###^
vma = Virtual Weather Monthly
Average Value
^vya###^
vya = Virtual Weather Yearly Average
Value
To view a complete list of the HTML tags, reference Figure
46 - HTML Tags. The HTML Tags window allows you to
easily cut and paste HTML tags into the template file.
^vvr###^
vvr = Virtual Weather Rate
^vrh###^
vrh = Virtual Weather Rate High
To select and copy a Tag to the clipboard, double click on
the selected parameter in the list. Next, paste the Tag into
your HTML template.
^vrt###^
vrt = Virtual Weather Rate High Time
^vrl###^
vrl = Virtual Weather Rate Low
^vrs###^
vrs = Virtual Weather Rate Low Time
Los Angeles International Airport (KLAX)
Temperature: ^mtr004KLAX^°F
where the mtr004 is the METAR tag for outdoor
temperature, KLAX is the METAR designator for Los
Angeles International Airport, and ^ is the parsing
character.
File Tags. You can specify the path of any file specified on
the File Tags list. For example:
^c:\vws\data\daily.txt^
where c:\vws\data\daily.txt is the complete file path and ^
is the parsing character. For more information for adding a
file path to the tag list, reference Section 8.14, HTML File
Tags.

Ftp Operation
The File Transfer Protocol (FTP) is part of the TCP/IP
protocols for data transmission on the Internet and is used
mainly to transfer files between computers. FTP is a clientserver protocol in which an FTP server waits for FTP
clients to connect to the server and issue requests.
ü
Server Name (for example, ftpwww.earthlink.net)
ü
User Name
ü
Password
ü
Select [OK].
The initial directory is optional.
Menu Shortcut: Internet u FTP Login [Login]
Generally, FTP servers require clients to provide a
username and password before processing any requests. An
FTP server administrator determines the user access policy
for the server. Many FTP servers allow anonymous access,
with restrictions, to the server. To log onto an FTP server
anonymously, clients enter anonymous as the username and
their e-mail address as the password.
Virtual Weather Station provides FTP Client functions that
connect to, and perform operations on, a specified FTP
server. Virtual Weather Station does not provide functions
that let your program behave as an FTP server. When your
program calls the FTP Client functions, it connects to an
FTP server which typically is running on a remote

these broken links, select the Create Temporary File First
on the Server. This option creates a file tempfilename.jpg,
and then copies tempfilename.jpg to filename.jpg. The
process of renaming a file on the server takes much less
time than transferring the file to your server, avoiding the
broken links.

METAR
General Description
Beginning 1 July 1996, the United States undertook the
most significant change for observing, reporting, and
coding surface weather observations and terminal forecasts
in the past forty years. Not since the early 1950s, when the
present airways code (commonly known as Surface
Aviation Observation or SA code), and Terminal Forecast
(FT) codes were adopted, has there been such a major code
change for weather observations and forecasts.
Attachments. Send attached weather data files.
On 1 July 1996, the international standard code
for hourly and special surface weather
observations, METAR/SPECI, took effect.
The METAR acronym roughly translates from the French
as Aviation Routine Weather Report . A special report,
SPECI, is merely a METAR formatted report which is
issued on a non-routine basis as dictated by changing
meteorological conditions.
The SPECI acronym roughly translates as Aviation Selected
Special Weather Report . Meanwhile, the international
standard code format for terminal forecasts issued for
airports, TAF , also took effect. The acronym translates to
Aerodrome Forecast .
Figure 56: Automatic E Mail Settings
8.16.2
Weather Reports
Periodic weather reports can be sent based complex user
defined schedule. To view the schedule, select the calender
from the panel.
The weather report sends the parameters specified in the
File Settings Panel. To view, this panel, select the
parameter icon from the panel. The names and units are
based on the entries, providing foreign language support.
The Federal Aviation Administration (FAA), which
determines aviation requirements in the United States, has
determined that the domestic transition to the
METAR/TAF code is vital to the standardization of these
reports worldwide. The National Weather Service (NWS)
and Department of Defense (DOD) are complying with this
requirement.
The benefits of having the U.S. standardize to these new
code formats are as follows. Hourly and special
observations are used both as stand alone data for the sites
-75-
03/07/06
Virtual Weather Station User's Guide
and as inputs to global weather models for both analysis
and forecasting. It is this global use of each small bit of
information which drives the need for standardization.
Additionally, the increase in international flights between
the U.S. and other nations from more U.S. locations than
ever before lends itself to developing a more "seamless"
international standard for aviation. Moreover,
standardization becomes vital for the general aviation
community for flights from the U.S. to Canada, the
Caribbean Area, and Mexico.

Mesonet
Mesonet is a combination of the words "mesoscale" and
"network".
In meteorology, "mesoscale" refers to weather events that
range in size from a few miles to a few hundred miles.
Mesoscale events last from several minutes to several
hours. Thunderstorms and squall lines are two examples of
mesoscale events.
A "network" is an interconnected system.
Thus, the Weather Underground Mesonet is a system
designed to measure the environment at the size and
duration of mesoscale weather events.
Figure 69 – Mesonet Settings
8.18.1.6.2 Mesonet Report
Your weather station is an important tool for meteorologists
and hobbyists to predict local weather conditions. It is
important you maintain your weather station, including
proper installation and calibration.
Virtual Weather Station allows you perform an “end-to-end
calibration” by applying a gain and offset to the measured
parameter.

10 Troubleshooting Tips
Problem
Solution
The program is not communicating to the
weather station (the instrument panel is
not updating)
Verify you have selected the correct Weather Station in Virtual Weather Station. To
view this winow, select the menu item Communication | Communication.
Verify that you have the correct communication port selected. If you are unsure
which comport is correct, select [Start][Settings][Control Panel] from the
windows menubar and select [System][Device Manager] and Ports. If COM1 is
designated, your comport is Communication Port 1.
Verify you are using the proper cable. A standard 9-pin serial cable is required. Do
not use a NULL modem cable.
If another program is using the serial communication port, quit the program. Two
programs can not share the same serial port.
If you own a Palm Pilot or similar device (such as a digital camera), the software is
often configured to open at startup of your computer, and “steals” the serial
comport, even if the device is not connected. Select “Ctrl-Alt-Del” once, and see if
any external device software is running.
Verify your station is not running on batteries and is connected to AC power.
Your communication port is locked-up. Cycle power to the computer
Your weather station console's communication port is locked up. Cycle power to
the console.
You have a hardware device conflict. It is recommended that you contact your PC
vendor or PC technical support .
Your serial port uses a non-standard IRQ line
-90-
03/07/06
Virtual Weather Station User's Guide
Problem
Solution
Your serial port is defective
Your weather station serial port is defective. Unplug the station's AC adapter from
the utility and run the station on battery power. If the LEDs display communication,
reconnect the station's AC adapter. If the unit stops communicating again, contact
Oregon Scientific.
See Advanced Communication Troubleshooting Tips
Communication only occurs while on the
batteries and not the AC.
If RTS (request to send) control line is low, communications will only occur when
on batteries. This condition will occur if you are using a 3-wire (pins 2,3,7) serial
cable, or if for some other reason, the computer serial port is not asserting RTS.
Use a standard 9-pin serial cable.
A script error or fatal error occurs during
installation.
Close all programs before installation. If the problem persists, reboot your
computer and make sure no programs are running.
Turn off the virus protection. This can interfere with the installation process.
The program crashes or you receive the
following Windows Message:
If your microprocessor is overheating, you may receive this message from the
operating system. Keep your computer in a cool place to reduce crashes
"This Program Has Received an Illegal
Operation and Will Shut Down"
Some low power mode or power savers will cause the program to crash when
communicating to the serial port. Turn off the power saver by selecting Right Click
on the desktop, Properties, Screen Saver, Settings (Energy Savings Features of
Monitor), and Turn off monitor.
Your graphics or display card driver may be outdated or incompatible. Virtual
Weather Station uses high resolution graphics that all display drivers must support.
However, display cards and their associated drivers are notorious for
incompatibilities with the Windows Operating System. You can determine your
graphics card manufacturer by selecting Right Click on the desktop, then Display
Properties, Settings and Advanced Properties. You may be able to
download the latest graphics driver from the manufacturer by performing a search
on the adapter part number and chip type.
The mouse moves on it's own or does not
operate after launching the software.
You have an IRQ conflict between the serial port and the mouse.
The solution is to replace your serial mouse with a bus mouse that resides on IRQ12. This is not a problem with the software but is a hardware conflict associated
with your computer. For more on IRQs, see Microsoft's troubleshooting hints.
How do I find the longitude and latitude
for my location?
You can contact your local town hall or city administration, but the best source of
information is on the Internet.
MapBlast at www.mapblast.com provides this information. Enter your address and
the longitude and latitude will be displayed in decimal form. Select this link and the
information will be converted to the degree format.

Problem
Solution
The celestial calculator is a close approximation of the sunrise and sunset in your
location and may be inaccurate by several minutes due to equation inaccuracy or
your altitude (the equations are based on sea-level).
You can account for this inaccuracy by entering a number in the offset (-60 minutes
to +60 minutes).
Sunrise and sunset are off by one hour, or
did not change with the Daylight Savings
Time Change.
This problem may be related to the operating system's daylight savings time clock.
The clock may not be available on your system.
To account for this problem, enter an offset of +60 minutes or -60 minutes.
The strip charts lose the data when the
program is shut down
Strip charts are intended for plotting data "real-time" and the data is not saved
permanently to a file. Reference the section on graphs vs. strip charts.
The minimum and maximum daily values
are not correct
Virtual Weather Station must be running to record daily highs and lows (data not
stored in your weather station's memory).
Rate of changes are not correct
Rate of change is set to zero when Virtual Weather Station is started.
Virtual Weather Station calculates the rate of change by calculating the derivative of
a parameter, and then filtering it over one hour. Thus, the rate of change equation
factors all of the measurements taken in the last hour, and may not exactly match the
change in one hour. Determining the actual change in one hour would require every
measurement within the hour to be saved, which is not practical, and would require
the software to be operational for more than one hour. Instead, Virtual Weather
Station uses calculation techniques standard in the engineering community for
calculating rate of change.
Virtual Weather Station's rain rate may not agree with the rain rate calculated by the
weather station because different techniques are used.
How do I display more decimal points for
a parameter?
Change the precision from the display's attributes panel. For example, changing the
precision to three will add three numbers to the right of the decimal point
(1/1000ths).
The jpeg images are distorted
Power save mode must be turned off to prevent distorted images
Weather display image colors are poor
quality
Virtual Weather Station prefers to run at High Color or 16 bit. Select
[Start][Settings][Control Panel] from the windows menubar and select
[Display][Settings] and High Color.
The software is consuming too much
CPU resources
Select [Program Settings][Program Settings] and set the CPU resources to Low.
Select [Internet][FTP General Settings] and set the FTP Priority to Below Normal
and select the Max CPU During FTP to OFF.
Select [Communication][Communiaction], and set the Communication Rate (sec) to
3.0 seconds or greater.
The graphical images are missing
You may be low on memory. Reduce the number of graphical images displayed.
The computer is low on memory
Reduce the number of displays. Too many displays may result in insufficient
memory.
The graphs update slow or the program
locks up when displays are updated
Reduce the length of time in your graphs. Select Plot Last x hours. Enter a number
less than 240 hours (for example). Plotting 20,000 points on multiple graphs can
cause long delays.

The font size is incorrect after changing
the font type
Changing font type can also change the font size due to font size limitations. To
restore default fonts, select the Default button from the font settings window and
restart the program.
The Moonrise (or Moonset) is showing -- instead of the time
Approximately once a month, the moon does not rise (or set) on a given day.
There is no data in my graph or
distribution chart when the program is

The chart will be empty if (1) the database is empty (example, when the program is
first started, or (2) Data has not been collected in the plot time frame specified in the
attributes window (the program was turned off).
The data in my graph is wrong. How can
I fix it?
This problem is generally a result of bad sensor data from your station, but can be
repaired in your database.
The data shown in graphs is stored in the database. To fix this data, go to
[Settings][Database Settings] and edit the database.
The data in my NOAA reports is wrong.
How can I fix it?
This problem is generally a result of bad sensor data from your station, but can be
repaired in your archive memory.
The data shown in the NOAA reports is stored in the archive memory.
To fix this data, go to [Settings][Daily Archive], [Settings][Monthly Archive] or
[Settings][Yearly Archive] and edit the data.
The data looks overwritten when opened
from the file folder in Virtual Weather
Station
Virtual Weather Station launches Notepad to view text files. This is a problem with
Notepad. Use another text editor such as Microsoft Word or Wordpad to view the
data.
The display image colors are poor quality
Virtual Weather Station prefers high resolution or 16-bit color. Some images may
result in poor quality at lower resolution settings.
The numerical markers on the ribbon and
temperature displays are not evenly
spaced
The software attempts to put a numerical marker at even increments, but this is not
always possible. To improve your numerical marker increments, select a high and
low range value that results in a difference of a multiple of 10. For example, a low
of -40 and a high of 60 will provide a difference of 100. This will produce better
marker increments then a low of -20 and a high of 100.
The Dew Point of the weather station is
reporting "LL" or limited to 32°F (0°C)
and Virtual Weather Station is reporting a
value
The Oregon Scientific unit does not report dew points below 32°F (0°C) but Virtual
Weather Station continues to report these values.
The sea-level barometer does not report
what is entered in the Station Settings
window.
Virtual Weather Station only reports the sea-level barometer from your station.
Reference Section 6.7.6 for more details.
The software is reporting a cloud base
when there are no clouds in sight.
This is only an estimate based on relative humidity and temperature. Other weather
parameters affect the cloud base, and should only be used as an estimate.
A Virtual Weather Station parameter
displays a different number than the
station console
Make sure that you have not entered a calibration (reference Chapter 6.3). Changing
the calibration of a sensor will not change the value on the display.

Problem
Solution
The Daily Rain is not correct
The program must be running at midnight for today's daily rainfall to be correct.
The Weather Station does not store daily rainfall.
The monthly rainfall reported in the
NOAA report does not agree with the
sum of the daily rainfall.
This is due to the station total rainfall reset by the user, or the values for minimum
or maximum rain edited by the user. Reference 6.19.2 for more details to correct
this.
How do I change my NOAA report data?
This is done in the Archive Settings window, and not the database. Reference
Section 7.2 for more details.
When I update one of the fields in the
daily summary data, this change is not
updated in the monthly or yearly
summary data.
You must edit each of these data fields. For example, if the minimum temperature
on January 9, 2000 is changed, and it is the minimum for the month and year, you
must change this field in the monthly summary panel and the yearly summary panel.
The Alarm Sound will not play
This feature requires a sound card.
This is not a problem with VWS, but with your sound card. Contact your sound
card manufacturer
Some of the check boxes on the
Parameters Display Panel are dimmed
Not all parameters can be displayed with all of the weather elements. For example,
graphs require historical data, and it does not make sense to plot sunrise.
The displays do not retain their position
when exiting the program.
Make sure you have enough memory in your computer to save the displays. The
display positions are saved in the file VWS\setup\position.bin. If this file is
corrupted, close VWS, delete this file and restart Virtual Weather Station. You will
need to reset the displays again.
Try a different drive. The drive you installed Virtual Weather Station on may be
read only.
After hiding Virtual Weather Station with
the taskbar icon, and recalling the display
by double clicking on the taskbar, the
window does not refresh
This is a Windows problem. Minimize and maximize the application again to
refresh.
One of the sensors is not updating, and
VWS will not begin executing (WMR918 or WMR-968 only).
Virtual Weather Station requires all of your sensors to operate to properly obtain
data. If one sensor is not functioning due to batteries or interference, deselect this
sensor. See Section 6.5.6, Sensor and Battery Status (WMR-918 and WMR-968
only) for more details.
My system clock is losing time when I
run Virtual Weather Station.
Use the Synchronization feature in Virtual Weather Station. Select Settings |
Synchronize Date and Time from the menubar. Note - you must be the administrator
on an NT machine for this to work.
You may have a bad ROM BIOS chip.
You may need a new battery on the motherboard.
Power management software in Windows can cause clock time loss.
It may be a Windows 95 and 98 problem. Windows NT handles this better because
of the operating system design.
When you connect your weather station to the communication port, Windows must
process interrupts to read this data. With weather stations, this occurs every 3
seconds. This causes the clock to slow down.

Virtual Weather Station User's Guide
Problem
Solution
If your computer is running other utilities, the clock speed may be affected even
more.
Your computer may need a tune-up. Here are some useful hints:
1) Don't run continuous virus checking. Have virus scanner scan your files on a
batch basis. Continuous virus checking slows down your computer.
2) We have had excellent luck with two parts of Norton Utilities:
(a) Norton Optimization Wizard (gets your swap file to the right size)
(b) WinDoctor.
Run both monthly and let them tune your computer.
3) If you have a number of programs running in the taskbar or resident to your
system, delete them. When you close all your programs you should only see about
6-7 programs in your task list.
4) Get enough memory (>64Mb).
5) Run as few real mode drivers as possible (take everything out of your autoexec
and config.sys).
6) Its fun to load a lot of programs to try them out, but every one of them leaves
traces behind in the form of .vxd's, .dll's, and registry entries that will
eventually slow up your system beyond repair. In the meantime, they slow it down
and cause odd functionality.
7) If all else fails, reinstall Win98. Don't just reinstall over your existing windows
directory, either. Wipe out c:\windows and c:\program
files and start again. You may have to spend 4 hours reinstalling your apps, but your
computer will run faster, you will use less disk space, and it will be more reliable.
Download a Clock Synchronization program, which synchronizes with the atomic
national clock. One example is www.beaglesoft.com
The language does not change when
changed from English
Virtual Weather Station provides limited foreign language support. To change the
titles to the language of choice, edit each individual display.
What are channels 1, 2 and 3?
Channels 1, 2 and 3 are designated channels for the optional sensors.
I receive Invalid Page Faults and General
Protection Faults in Kernel32.DLL
Invalid Page Faults and General Protection Faults in Kernel32.DLL are generally
caused by a lack of system resources, out of date video drivers, or a corrupt
swap/paging file. If you encounter the problem on a regular basis, the following
instructions should help resolve the problem:
Windows 95 users ONLY. (Windows 98 users proceed to step 2.)
If the kernel32.dll error occurs while you are browsing and you are using
Windows 95, this problem could be occurring due to Windows 95 bug.
The bug is present in earlier versions of Windows 95 and Microsoft has
posted an update which resolves the problem. In order to determine which
updates you need, right-click on the My Computer icon on your desktop
and select Properties from the menu. Click on the General tab to make

Memory leaks are common with the Microsoft Operating System if functions are
repeated over and over again (for example, When you run a program that uses
Windows Sockets in Windows 95, a gradual increase in the memory used by the
operating system may occur over time, especially if the program opens and closes a

11 Glossary of Terms
The following is a glossary of weather and instrument terms.
Term
Definition
AIR DENSITY
The ratio of the mass of a substance to the volume it occupies. In oceanography, it is
equivalent to specific gravity and represents the ratio of the weight of a given volume of
sea water to that of an equal volume of distilled water at 4.0 degrees Celsius or 39.2
degrees Fahrenheit.
ATMOSPHERIC PRESSURE
See barometric pressure
BAROMETRIC PRESSURE
The pressure exerted by the atmosphere as a consequence of gravitational attraction
exerted upon the "column" of air lying directly above the point in question. The
measurement can be expressed in several ways. One is in millibars. Another is in inches or
millimeters of mercury (Hg). Also known as atmospheric pressure.
BEAUFORT WIND SCALE
A system of estimating and reporting wind speeds. It is based on the Beaufort Force or
Number, which is composed of the wind speed, a descriptive term, and the visible effects
upon land objects and/or sea surfaces. The scale was devised by Sir Francis Beaufort
(1777-1857), hydrographer to the British Royal Navy.
CALIBRATION ERROR
The inaccuracy that the manufacturer permits when the unit is calibrated in the factory.
CLOUD BASE
For a given cloud or cloud layer. The lowest level in the atmosphere at which the air
contains a perceptible quantity of cloud particles. Virtual Weather Station estimates the
cloud base on temperature and humidity readings, using the following equation:
Cloud Base (ft) = 250(Temperature - Dew Point)
COOLING DEGREE DAY
A cooling degree day is given for each degree that the daily mean temperature departs
above the baseline of 75 degrees a given temperature It is used to estimate the energy
requirements, and is an indication of fuel consumption for air conditioning or
refrigeration. Refer to degree day or heating degree day.
DEW POINT
The temperature to which a sample of air must be cooled, while the mixing ratio and
barometric pressure remain constant, in order to attain saturation by water vapor. When
this temperature is below O°C, it is sometimes called the frost point.
-98-
03/07/06
Virtual Weather Station User's Guide
Term
Definition
GUST
A sudden significant increase in or rapid fluctuations of wind speed. Peak wind must reach
at least 16 knots (18 miles per hour) and the variation between peaks and lulls is at least 10
knots (11.5 miles per hour). The duration is usually less twenty seconds.
HEAT INDEX
The combination of air temperature and humidity that gives a description of how the
temperature feels. This is not the actual air temperature.
HEATING DEGREE DAY
One heating degree day is given for each degree that the daily mean temperature is below
65 degrees a given temperature. It is used as an indication of fuel consumption. Refer to
degree day or cooling degree day.
HUMIDITY
The amount of water vapor in the air. It is often confused with relative humidity or dew
point. Types of humidity include absolute humidity, relative humidity, and specific
humidity.
LATITUDE
The location north or south in reference to the equator, which is designated at zero (0)
degrees. Parallel lines that circle the globe both north and south of the equator. The poles
are at 90 degrees North and South latitude.
LONGITUDE
The location east or west in reference to the Prime Meridian, which is designated as zero
(0) degrees longitude. The distance between lines of longitude are greater at the equator
and smaller at the higher latitudes, intersecting at the earth's North and South Poles. Time
zones are correlated to longitude. See Greenwich Mean Time.
MOON PHASE
The moon phase is caused by sun rays reflecting off the moon's surface while it moves
around the earth. The sun illuminates half of the moon at any time while the moon orbits
around the earth. The variation in the angle made by the earth-moon line with respect to
the earth-sun line causes changing phase of the moon.
The moon completes one revolution around the earth in 27.322 days with respect to the
background stars. This is called the SIDERIAL period of the moon. During this same time
the earth moves about 27 degrees along its orbit around the sun. As a result, the moon
takes about two extra days to complete the cycle with respect to the sun-earth line. This
longer cycle of the moon that takes about 29.57 days is called SYNDONIC period of the
moon. The longer cycle is considered as Lunar month.
PRESSURE ALTITUDE
Atmospheric or barometric pressure expressed in terms of altitude which corresponds to
that pressure in the standard atmosphere.
RATE OF CHANGE
The derivative or change in a parameters value with respect to time. Virtual Weather
Station calculates the rate of change by calculating the derivative of a parameter, and then
filtering it over one hour. Thus, the rate of change equation factors all of the
measurements taken in the last hour, and may not exactly match the change in one hour.
RELATIVE HUMIDITY
A type of humidity that considers the ratio of the actual vapor pressure of the air to the
saturation vapor pressure. It is usually expressed in percentage.
SEA LEVEL PRESSURE
The atmospheric pressure at mean sea level either directly measured by stations at sea
level or empirically determined from the station pressure and temperature by stations not
at sea level. Used as a common reference for analyses of surface pressure patterns.
SUNRISE
The daily appearance of the sun on the eastern horizon as a result of the earth's rotation. In
the United States, it is considered as that instant when the upper edge of the sun appears
on the sea level horizon. In Great Britain, the center of the sun's disk is used instead. Time
of sunrise is calculated for mean sea level. See sunset for comparison.
SUNSET
The daily disappearance of the sun below the western horizon as a result of the earth's
rotation. In the United States, it is considered as that instant when the upper edge of the
sun just disappears below the sea level horizon. In Great Britain, the center of the sun's

sun just disappears below the sea level horizon. In Great Britain, the center of the sun's
disk is used instead. Time of sunset is calculated for mean sea level. See sunrise for
comparison.
VAPOR PRESSURE
The pressure exerted by water vapor molecules in a given volume of air
VIRTUAL TEMPERATURE
Virtual temperature is a fictitious temperature that takes into account moisture in the air.
The formal definition of virtual temperature is the temperature that dry air would have if
its pressure and specific volume were equal to those of a given sample of moist air. Virtual
temperature allows meteorologists to use the equation of state for dry air even though
moisture is present.
WIND CHILL INDEX
The calculation of temperature that takes into consideration the effects of wind and
temperature on the human body. Describes the average loss of body heat and how the
temperature feels. This is not the actual air temperature.
WIND DIRECTION
The direction from which the wind is blowing. For example, an easterly wind is blowing
from the east, not toward the east. It is reported with reference to true north, or 360
degrees on the compass, and expressed to the nearest 10 degrees, or to one of the 16 points
of the compass (N, NE, etc.).
WIND RUN
The distance or length of flow of the air past a point during a given interval of time.
WIND SPEED
The rate of the motion of the air on a unit of time. It can be measured in a number of ways.
In observing, it is measured in knots, or nautical miles per hour. The unit most often used
in the United States is miles per hour.
