3.1 Test Run The Bufkit package comes with preconfigured to display data in the Case Study directory. Seve
sample profiles were included in this directory. You can run Bufkit either by Double Clicking the Bufkit3.exe i
within the Bufkit3 directory.
You can also ese the Windows menu system by clicking on the Start button. Click on the Start > Programs >
Ensure Windows can display at least 800x600 resolution. Any resolution will work with the exception of the Wi
default resolution of 640x480. At one time, over 30% of the installation problems for BUFKIT deal with not sett
the display driver in at least 800x600 resolution.
3.2 Configuring BUFKIT for your Site. Edit the file BUFKIT.CFG with a text editor (or any word processor that ca
ASCII format). The format of this configuration file is a description line followed by the configuration value. The
description line can contain any words, but it must be present. If a description ends with a "*", then you must e
entry to get BUFKIT working properly. Note you no longer have to end a directory with a "\", it is optional. How
watch out for training extra spaces at the end of any entry.

3.4 Getting Bufkit Profiles.
3.4.1 Generating Profiles On-Station. National Weather Service offices have the capability of generating thei
BUFKIT-compatable profiles from using a Unix workstation or a Linux PC using Gempak. (Note: It has been our
experiance that any Pentium-class Linux Box with at least 64 MB of RAM will out perform our SAC by at least 2
Bob Rozumalski, the National Weather Service SOO/SAC coordinatior, has worked with NCEP to create a script
MODSND to automatically retrieve forcast profiles from NCEP and reformat them into a BUFKIT-compatable for
NWS offices can can download the MODSND script from the SOO/SAC contrib directory. Once you generate th
profile on your workstation, you must make it accessable to the PC running BUFKIT. You have two choices.
3.4.1.1 FTP. The simplest method is to FTP the data to your PCs. Most offices are currently using this method.
you FTP the data make sure you use the BINARY transfer mode.
3.4.1.2 SAMBA. The most effective method to provide BUFKIT access to the generated ASCII files is by installin
utility SAMBA on your SAC or Linux PC. Once installed, every Windows computer on your LAN has access to the
files contained on the workstation. Several offices in Eastern region have this valuable utility already installed
subset of SAMBA. The installation process for this subset typically takes less than 30 minutes. Paul Sisson, SO
Burlington, VT has developed the following procedures to get SAMBA up and running on your SAC.
This is for Samba for HPUX 9.0X
(Note: Paul reports this works for HPUX10 also.)
0) Download the HPUX SAMBA tar file from here.
samba is installed in /usr/local as root
1)untar samba.tar in /usr/local
cd /usr/local
tar -xvf samba.tar
2)cd /usr/local/samba/lib
3)edit smb.conf
change workgroup to your site's Windows workgroup name NOTE: Look in Network Neighborhood under
Network to see what your workgroups names are.
change [DosMetdat] to whatever name you want to show up in windows.
change the path= to name of directory you want to share
************** example of smb.conf to share a directory to windows************
[global]
mangle case = yes
mangled names = yes
default case = lower
case sensitive = no
preserve case = yes
short preserve case = yes
default service = reference
workgroup = btv
guest account = gempak
lock directory = /usr/local/samba/var/locks
share modes = yes
[DosMetdat]
path = /usr2/metdat/dos
public = yes
only guest = no
writable = yes
printable = no

4) to start samba daemons:
smbd must be executed first
nmbd must be executed second
from the prompt as root:
/usr/local/samba/smbd
/usr/local/samba/nmbd
You can add the 2 lines to the localrc() section of /etc/rc
to start samba at boot time:
5) Thats about it. You should go to win95 and see the directory in Network
Neighborhood. You can then map it to a drive.

3.4.2 Downloadling Profiles off the Internet. Hundreds of BUFKIT profiles are posted by National Weather Ser
offices and the The Department of Meteorology at Penn State on the internet. See
http://www.erh.noaa.gov/er/buf/bufkit/prof.html for links to the various web locations.
3.4.2.1 Downloading profiles using Netscape. Downloading profiles using Netscape is easy. However, Netsca
only correctly download profiles using the FTP protocol. If the profile is being offered from a NWS web page us
protocol use Internet Explorer (see 3.4.2.1).
Move your cursor over the station you
want to download. Right-Click the
mouse and a pop-up menu will appear.
Select the Save Link As... menu option.
A File Dialog Box will open up.
Change the directory to the one that
contains your forecast profiles. Then
click the Save button.
3.4.2.2 Downloading profiles using Internet Explorer.

Change the directory to the one that
contains your forecast profiles. Note
Internet Explorer will try to save the file
as a Text Document. This would be
compatable with Bufkit except that is you
clicked the Save button now the file
would be saved with a .txt extension
appended to the file name.
In this case, if you clicked the Save
button now, the file would be saved as
metakit.gsp.txt
To overcome this limitation, just place
quotes (i.e. the " character) around the
file name. Now when you select the Save
button, the profile will be saved under its
correct name. In this case metakit.gsp
3.4.2.2 Downloading profiles using BufGet. Downloading individual profiles can be tedious of you routinely re
site. The problem is worse if you want to routinely retrieve several sites. The BufGet software package addre
these problems. You identify up to four lists of profiles that you may want to download. A list may contain pro
several different NWS offices and combine HTTP and FTP transfers. The program with detailed instructions are
available at http://www.erh.noaa.gov/er/buf/bufkit/bufget.html
4.0 Profile Mode. BUFKIT has two major display modes. The PROFILE display presents an analysis of a single ho
profile data. The OVERVIEW display presents a time line of parameters from the entire model run. BUFKIT start

temperature is increasing with height greater than a threshold (0.5oC per layer)
nearly isothermal (temperature change less than 0.5oC per layer) and the dewpoints rapidly decreasing w
height.
4.4.1.8 2M Temp. Displays the 2 meter temperature and dewpoint on the profile display in the following form
Temp°C/Dew Point°C
4.4.1.9 Skew-T. When selected the temperate axis is similar to a Skew-T diagram. When not selected, the plot

4.4.1.15 Momentium Transfer.
This technique, developed at WFO
Tauton and WFO Burlington,
indicates the potential for
upperlevel winds to mix down to
the surface. The display is
computed as follows: Starting at
the surface, go up the temperature
profile until the temperature
decrease is no longer close to the
dry adiabatic lapse rate. Bufkit
highlights this portion of the
temperature profile in light red and
displays the wind speed and
direction at that top level. Bufkit
then computes the vector mean
wind within that layer.
