RAWS-F Remote Automated Weather
Station for Fire Weather
1. Introduction
The RAWS Quick Deployment Weather Station is a lightweight, preconfigured station that can be set up in less than 10 minutes—without tools
(see Section 2—Getting Started). The aluminum environmental enclosure
houses a 12 V rechargeable battery and a CR1000 datalogger mounted to a 6 ft
tripod. The outside of the enclosure has color-coded, keyed connectors (Figure
1-1) for attaching the sensors. Besides the connectors, a wiring panel is
included that allows the measurement of additional sensors. Communication
options include satellite transmitter and voice radio interface module.
Additional communication equipment (telephone, cellular phone, radio) can be
added to the station. This station is ideal for prescribed burns or other
temporary installations. The RAWS-F Quick Deployment Weather Station is
shown in Figure 1-2.

RAWS-F Remote Automated Weather Station for Fire Weather
3. Station Siting and Orientation
3.1 General Description
Selecting an appropriate site for the RAWS Quick Deployment Weather
Station is critical in order to obtain accurate meteorological data. In general,
the site should be representative of the general area of interest and away from
the influence of obstructions such as buildings and trees.
NOTE
WARNING
See Section 8 for siting references.
If any part of the weather station comes in contact with
power lines, you could be killed. Contact local utilities
for the location of buried utility lines before digging or
driving ground rods.
3.2 Air Temperature and Relative Humidity
A temperature and relative humidity sensor should be located over an open
level area at least 9 m in diameter (EPA). The surface should be covered by
short grass, or where grass does not grow, the natural earth surface. The sensor
must be housed inside a radiation shield and adequately ventilated.
Situations to avoid include: 1) large industrial heat sources, 2) rooftops, 3)
steep slopes, 4) sheltered hollow, 5) high vegetation, 6) shaded areas,
7) swamps, 8) areas where snow drifts occur, and 9) low places holding
standing water after rains.
3.3 Precipitation
A rain gauge should be located over an open level area covered by short grass,
or where grass does not grow, the natural earth surface. Level the RAWS
station to ensure the sensors are level. Level the rain gage by adjusting the rain
gage leveling screw. A post level and compass ship with the RAWS station
(part #16770).
NOTE
Take off the funnel and remove the rubber band securing the
tipping bucket mechanism during transport.
3.4 Solar Radiation
A solar radiation sensor should be located to avoid shadows on the sensor at
any time. Orient the RAWS station where the solar radiation sensor faces
south (northern hemisphere) minimizing the chance of shading from other
weather station structures. Reflective surfaces and sources of artificial
radiation should be avoided. Level the RAWS station to ensure the solar
radiation sensor is level.
6
RAWS-F Remote Automated Weather Station for Fire Weather
3.5 Wind Speed and Direction
A wind sensor should be located over open level terrain and at a distance of at
least ten times (EPA) the height of any nearby building, tree, or other
obstruction.
3.6 Barometric Pressure (optional)
The barometric pressure sensor is mounted to the back plate inside the RAWS
environmental enclosure.
3.7 Fuel Moisture and Fuel Temperature (optional)
The fuel moisture and fuel temperature sensor should be left outside at the field
site continually exposed to the same conditions as forest fuels. The fuel
moisture and fuel temperature dowel rods absorb and desorb moisture from its
surroundings. Install the probes horizontally on the mounting stake and face
the sensors south (northern hemisphere) above a representative forest floor duff
layer. Place the sensor away from foot traffic areas.
4. Sensor Maintenance, Calibration, and
Troubleshooting
4.1 Maintenance
Proper maintenance of weather station components is essential to obtain
accurate data. Equipment must be in good operating condition, which requires
a program of regular inspection and maintenance. Routine and simple
maintenance can be accomplished by the person in charge of the weather
station. More difficult maintenance, such as sensor calibration, sensor
performance testing (i.e., bearing torque), and sensor component replacement,
generally requires a skilled technician, or send the instrument to Campbell
Scientific. A station log should be maintained for each weather station that
includes equipment model and serial numbers and maintenance that was
performed.
NOTE
Contact Campbell Scientific, Inc., phone (435) 753-2342, for an
RMA number before returning sensor or equipment for service.
4.2 Air Temperature and Relative Humidity
4.2.1 General Description, Air Temperature and Relative Humidity (part
#HMP45C-QD)
The Vaisala Air Temperature and Relative Humidity Sensor (part #HMP45CQD) shown in Figure 4.2-1 contains a Platinum Resistance Temperature
detector (PRT) probe and a Vaisala HUMICAP® 180 capacitive relative
humidity probe. The probe output for each sensor is a voltage.

FIGURE 4.2-1. Air temperature and relative humidity
4.2.2 Wiring, Air Temperature and Relative Humidity (part #HMP45C-QD)
The temp/RH sensor is connected to the RAWS connector panel “TEMP/RH”
connector COLOR CODED ORANGE. This sensor is internally wired from
the RAWS connector panel to the CR1000 datalogger.

4.2.3 Maintenance, Air Temperature and Relative Humidity (part
#HMP45C-QD)
The temp/RH sensor requires minimal maintenance. Check monthly to make
sure the radiation shield is free from debris. The filter at the end of the sensor
should also be checked for contaminates. When installed in close proximity to
the ocean or other bodies of salt water, a coating of salt may build up on the
radiation shield, sensor, filter and even the RH chip. A buildup of salt on the
filter or RH chip will delay or destroy the response to atmospheric humidity.
The filter can be rinsed gently in distilled water. If necessary, the chip can be
removed and rinsed as well. Do not scratch the RH chip while cleaning.
8
RAWS-F Remote Automated Weather Station for Fire Weather
4.2.4 Calibration, Air Temperature and Relative Humidity (part #HMP45CQD)
Recalibrate the temp/RH sensor annually. Obtain a Return Material
Authorization (RMA) number before returning this sensor to Campbell
Scientific for recalibration.
4.2.5 Troubleshooting, Air Temperature and Relative Humidity (part
#HMP45C-QD)
Check the sensor cable. Disconnect the connector and look for damaged pins.
Verify that the sensor body is connected to the sensor head. Under the filter
assembly, verify the sensors are connected but not touching. Try connecting a
substitute sensor. Obtain a Return Material Authorization (RMA) number
before returning this sensor to Campbell Scientific for repair.
4.3 Rain Gage
4.3.1 General Description, Rain Gage (part #TE525-QD)
The Texas Electronics Rain Gage (part #TE525-QD) shown in Figure 4.3-1 is
an adaptation of a Weather Bureau tipping bucket rain gage. The rain gage has
a 6 inch collector. The rain gage sensor output has a switch closure for each
bucket tip. Level the rain gage by adjusting the rain gage leveling screw. A
post level and compass (part #16670) ship with the station.

4.3.3 Maintenance, Rain Gage (part #TE525-QD)
The rain gage funnel and bucket mechanism must be kept clean. Routinely
check for and remove any foreign material, dust, insects, etc.
4.3.4 Calibration, Rain Gage (part #TE525-QD)
Recalibrate the rain gage annually. Obtain a Return Material Authorization
(RMA) number before returning this sensor to Campbell Scientific for
recalibration.
4.3.5 Troubleshooting, Rain Gage (part #TE525-QD)
Check the sensor cable. Disconnect the connector and use a DVM to check the
resistance between Pin A (sensor signal) and Pin C (sensor ground). The
resistance should read as an open circuit until you move the rain gage tipping
mechanism where the magnet swings past the reed relay. Try connecting a
substitute sensor. Obtain a Return Material Authorization (RMA) number
before returning this sensor to Campbell Scientific for repair.
4.4 Solar Radiation
4.4.1 General Description, Pyranometer (part #CS300-QD)
The Apogee Pyranometer (part #CS300-QD) shown in Figure 4.4-1 measures
incoming solar radiation with a silicon photovoltaic detector mounted in a
cosine-corrected head. The detector outputs current; a shunt resistor in the
sensor converts the signal from current to voltage. During the night the
CS300-QD may read slightly negative incoming solar radiation. The negative
signal is caused by RF noise.

Troubleshooting
5.1 Solar Panels (part #SP10/20-QD)
5.1.1 General Description, Solar Panel (part #SP10/20-QD)
The RAWS Solar Panel is a photovoltaic power source used for charging lead
acid batteries. The SP20-QD 20 watt solar panel is used for system
configurations that have higher-than-average power requirements. It is also
recommended for use at higher elevations and latitudes. The solar panel
should be mounted facing south if located in the northern hemisphere, or facing
north in the southern hemisphere.
The SP10-QD 10 watt solar panel is recommended for a RAWS Quick
Deployment Weather Station where NO communication equipment is used.
The SP20-QD 20 watt solar panel is recommended for a RAWS Quick
Deployment Weather Station where communication equipment is used (i.e.,
GOES, voice, cell phone, or radio).
NOTE
The solar panel selected for the RAWS Quick Deployment
Weather Station depends on the station power requirements,
specifically the communication equipment selected for the
station.
The SP10-QD solar panel outputs 0.59 Amps, 8.9 Watts typical peak power.
The SP20-QD solar panel outputs 1.17 Amps, 18 Watts typical peak power.
5.1.2 Wiring, Solar Panel (part #SP10/20-QD)
The RAWS-Solar Panel (part # SP20-QD or SP10-QD) attaches to the
connector panel labeled “BATT CHARGER/SOLAR PANEL”. Inside the
RAWS environmental enclosure the “BATT CHARGER/SOLAR PANEL”
connector pin A and pin B are wired to the CH100 charger/regulator “CHG”
and “CHG” ports. Polarity does not matter; either lead can be connected to
either terminal. The CH100 charger/regulator has two functions: 1) blocks any
current flow from the battery to the solar panel, and 2) limits the source current
to the battery.
17
RAWS-F Remote Automated Weather Station for Fire Weather
5.1.3 Maintenance, Solar Panel (part #SP10/20-QD)
An occasional cleaning of the glass improves the solar panel’s efficiency.
5.1.4 Calibration, Solar Panel (part #SP10/20-QD)
No calibration is required.
5.1.5 Troubleshooting, Solar Panel (part #SP10/20-QD)
If a problem with the solar panel is suspected, the solar panel may be checked
by measuring the voltage output from the solar panel. Check the voltage with a
voltmeter connected between the two leads going to the CH100
charger/regulator “CHG” “CHG” terminals located inside the environmental
enclosure (15 VDC to 28 VDC). There must be solar radiation incident on the
panel and there must be a load connected to the solar panel. The load can be
the datalogger, other equipment, or a 75 ohm resistor capable of dissipating
solar panel power between the two leads. No voltage output implies a bad
solar panel, regulator, or cable. The magnitude of the voltage output depends
on the incident solar radiation. Check the sensor cable. Disconnect the
connector and look for damaged pins. Try connecting a substitute panel.
Obtain a Return Material Authorization (RMA) number before returning the
SP10/20-QD to Campbell Scientific for repair.

5.4 GOES Transmitter (part #TX312) (Optional)
5.4.1 General Description, GOES Transmitter (part #TX312)
The High Data Rate GOES transmitter (part #TX312) shown in Figure 5.4-1
supports one-way communication, via satellite, from a Campbell Scientific
datalogger to a ground receiving station. Satellite telemetry offers a convenient
communication alternative for field stations where phone systems or RF
systems are impractical or rendered unreliable after a tragedy to the local
infrastructure. Data transmission rates of 100, 300, and 1200 bps are
supported. Because clock accuracy is critically important for GOES satellite
telemetry, the TX312 includes a robust, TCXO-based real-time clock and a
GPS receiver.
The TX312 transmitter has two siting requirements for proper operation. The
GOES antenna must have a clear view of the spacecraft. The GOES antenna is
directional and should be aimed at the spacecraft. Both elevation and azimuth
are unique to the location of the planet and must be set. A poorly aimed
antenna will cause a drop in signal strength or possibly prevent successful
transmission.
For more information on the GOES transmitter (part #TX312) and antenna
siting, go to our website at www.campbellsci.com, enter the “TX312” in the
“Search” box on the website mentioned above, and go the equipment manual.
The GOES transmitter (part #TX312) manual is also provided on the Resource
CD which ships with the RAWS Quick Deployment Weather Station.
NOTE
The spacecraft specific DCP-Setup parameters for the GOES
transmitter must be entered in the CR1000KD menus for the
GOES transmitter TX312 to work properly. If the RAWS Quick
Deployment Weather Station does NOT have a GOES
transmitter disregard the DCP-Setup parameters.

5.7.4 Calibration, CR1000 Datalogger (part #CR1000)
Recalibrate the CR1000 datalogger every two years. Obtain a Return Material
Authorization (RMA) number before returning the CR1000 to Campbell
Scientific for recalibration.
5.7.5 Troubleshooting, CR1000 Datalogger (part #CR1000)
If a problem with the CR1000 datalogger is suspected, the CR1000 may be
checked by connecting the CR1000KD to the CR1000 printed circuit board 9Pin “CS I/O” connector using our CS I/O serial cable (part #10873). The
CR1000KD display should be visible. If the display is not visible, check the
CR1000 printed circuit board for 12 Volt power. If the CR1000 is
unresponsive to CR1000KD key strokes, then there might be a problem with
the CR1000 datalogger. If problems persist, try a substitute. Contact a
Campbell Scientific applications engineer for assistance. Obtain a Return
Material Authorization (RMA) number before returning this equipment to
Campbell Scientific for repair.
6. Desiccant
6.1 When to Replace Desiccant
A humidity indicator card and desiccant packs are provided with the weather
station. Place the humidity indicator card and 2 ea. desiccant packs inside the
enclosure. Desiccant packets inside the enclosure should be replaced with
fresh packets when the upper dot on the indicator begins to turn pink. The
indicator tab does not need to be replaced unless the colored circles overrun. A
humidity indicator card (part #6571) and desiccant pack (part # 4905) may be
ordered through Campbell Scientific. Desiccant packs inside of the datalogger
do not require replacement under normal conditions.
6.2 Reusing Desiccant
Customers can reactivate saturated desiccant packets. Care must be taken. If
the heating process is too rapid, water vapor is released too quickly causing too
much pressure to build up inside the packets so that the packets burst.
Standard Oven Method:
1.
Bake at an oven temperature of 125ºF for 2 hours.
2.
Increase the oven temperature to 175ºF and bake for 2 hours.
3.
Increase the oven temperature to 245ºF to 250ºF and bake for 12 hours.
The optimum situation for reactivation is to use a recalculating oven that has a
ramping temperature. The desiccant should bake for 16 hours, and the final
temperature should be 245ºF to 250ºF.

8.3 RAWS Orientation
8.3.1 Determining True North and Sensor Orientation
Orientation of the wind direction sensor is done after the datalogger has been
programmed and the location of True North has been determined. True North
is usually found by reading a magnetic compass and applying the site-specific
correction for magnetic declination; where the magnetic declination is the
number of degrees between True North and Magnetic North. Magnetic
declination for a specific site can be obtained from a USGS map, local airport,
or through the web calculator offered by the USGS (Section 8.3.2). A general
map showing magnetic declination for the contiguous United States is shown
in Figure 8.3-1.
Declination angles are always subtracted from the compass reading to find
True North. A declination angle east of True North is reported as positive a
value and is subtracted from 360 (0) degrees to find True North as shown
Figure 8.3-2. A declination angle west of True North is reported as a negative
value and is also subtracted from 0 (360) degrees to find True North as shown
in Figure 8.3-3. Note that when a negative number is subtracted from a
positive number, the resulting arithmetic operation is addition.
For example, the declination for Longmont, CO is 10.1°, thus True North is
360° - 10.1°, or 349.9° as read on a compass. Likewise, the declination for Mc
Henry, IL is -2.6°, and True North is 0° - (-2.6°), or 2.6° as read on a compass.

FIGURE 8.3-3. A declination angle west of True North (negative) is
subtracted from 0 (360) degrees to find True North
8.3.2 USGS Web Calculator
The USGS provides an easy way of determining declination of a specific site.
Since magnetic declination fluctuates with time, it should be adjusted each time
the wind sensor orientation is adjusted. The calculator can be accessed at:
www.ngdc.noaa.gov/geomagmodels/Declination.jsp. Figure 8.3-4 shows an
example for Logan, UT.
31
RAWS-F Remote Automated Weather Station for Fire Weather
FIGURE 8.3-4. USGS web calculator
In the example above the declination for Logan, UT is 12º 24′ or 12.4º. As
shown in Figure 9.3-4, the declination for Utah is east (positive), so True North
for this site is 360 – 12.4 = 347.6 degrees. The annual change is 7 minutes
west per year or -7 minutes/year.
