Hi

You all have the unique distinction of being registered on my degrib
mailing list (all 8 of us) (I'd like to welcome rdale, rwb, and Clark
Safford to the list). Since you are a member, you get this email...

Please let me know if you want to unregister.

I have just finished version "0.90" (last one was "0.85" on 11/20/2002)

New to this release:
1) Moved the web site from 140.90.10.88/degrib/ to
www.nws.noaa.gov/mdl/NDFD_grib2Decoder/

2) Fixed a number of minor bugs, including a correction for the naming
of "SNOW"

3) Introduced a -Unit option which allows one to output the data in F
instead of K. Use "-Unit english" for F, Knots, inches, "-Unit metric"
for C, m/s, m. Use "-Unit none" to get no unit conversion... (Useful if
the people who packed it didn't actually store a temperature in K like
they are supposed to). The default is now "-Unit english"

4) Handled a major bug with the Windows version... For second order
differencing the FORTRAN code needs an automatic array on the order of
2.8 megs. However the code on a PC was compiled with 2 megs of stack
space. It crashes (only on the PC). After some dead ends I finally
realized that I could use the option "-Wl,--stack,4000000" in my
makefile to get gcc to grab 4 megs of stack space. The code works now.

The following currently only affects the command line version:
5) Added a "-msg all" or "-msg 0" option to convert all the messages in
the file.

6) Added a "-namePath" option to allow one to use the -nameStyle but
store the files in a different directory.

7) Added a "-nameStyle 3" option (A new nameStyle to be compatible with
NDFD imageGen)

8) Added a "-P" option to allow one to probe a given lat/lon point in
all the messages in the file. It does this by linearly interpolating
the surrounding cells to that point. May want to do a nearest neighbor
instead. Also the -pntFile option is not working yet.

9) As always, tested on PC, Linux, HP-Unix, and AIX-Unix. Although I
may have missed something in my testing, it should at least compile, and
run for some of the test cases.

Ira:
What this means to you... Your current tcldegrib should work fine. It
is, however, using one of the dead ends that I traversed, and you don't
have the -P option (command line only), so although it should function
fine, you might want the current release.

Jerry:
What this means to you... I again have compiled current versions in
~taylor/degrib/bin on rainbow (HP-GDP), in ~taylor/degrib/bin on bd10
(linux), and in /nfsuser/g06/we25at/degrib/bin on Suitland's IBM. So
again, you shouldn't need to download the code or compile it yourself.

Ron:
Did my suggestions about ArcView help with regards to your "one solid
color"?

All:
If you are using the MS-Windows version, then I would definitely
recommend .90 over any of the earlier releases, mainly because of item
4)

Arthur
