[Release] Grb2fmap - GRIB to BMS Converter
-
I meant in between consecutive fmaps generated by my tool jp (as diditopgun claimed there was none), not inside BMS
EDIT: diditopgun, you can actually notice this interpolation in the video in the first post. Each frame is 1hr, GRIB data interval is 3hrs (aka 3 frames).
EDIT2: Actually, depending on the interval options you set on zyGrib (i.e. interval same than period), you will end up with only one TCDC and APCP record. In this case the “clouds” will be the same for all the files. This is to be expected as there is only one sample. I will think whether to generate only one file in that case for the next release, to avoid confusion. <–- done in v0.5c
EDIT3: Also, as the GRIB cloud cover/precipitation data (only) is encoded for a time range, it is normal for the first couple of hours (until there are two data sets to interpolate from) to show the same weathertype pattern, as there is no data to interpolate in this period, just the first record. There may be a little bit of room for improvement here with some smarter processing. I will take a look… <–- done in (not yet released) v0.5d

Does anyone know the GRIB map size that should be used to make FMAPs for the 4.33 ITO theater? Or, recommended GRIB coordinates?
Edit, nevermind …. found in post #1.
Also, are the corresponding BMS ITO coordinates needed and, if so, what are those?
-
These are one and the same. Just download the GRIB via ZyGRIB from the specified lat/long. Unzip the saved GRIB file then run GRIB2FMAP and point it at the GRIB you just downloaded. Simples!

Maybe someone can help me out here?
First off incredible tool BTW!!! It appears I have everything working, however. I cannot see the file to select to have it converted?? When I open the grb2fmap and click convert, it is pointing towards the correct folder, but it will not show the *.grb files?? They are in the folder, I can see them. But it will not show when trying to convert them, thus I cannot select the files??? Am I missing something???

Am I missing something???Yes, you are missing step 2 of the instructions
- Unzip the downloaded file
The file you download is compressed in .bz2 format. The program only accepts .grib files. You need to decompress your downloaded .bz2 file (most common archivers such as winrar, 7zip, etc will do it)
-
AHHH! Damn how did I miss that. lol
THANKS!
-
By default the GRIB downloads are compressed. You have to unzip (or whatever compression it uses) to get the files out of the compressed archive.

Just for those who didn’t notice, v0.5d is up with various small fixes for the issues that were raised over the week, with especial mention to improved interpolation of the weather type in the first few hours generated. Also, for those wanting to match the GRIB forecast times with the BMS time, this is now output to the log window too.
I am also waiting for the answer from the zyGrib developer to the matter of allowing us to use his GRIB data server from within the tool. If it is positive you can expect that option in the future. That should make a little bit more straightforward the process of converting the weather (and most likely allow automatically matching the timezone for those who want that). If not, unless some more issues pop up, this should be final for a long time.

I’ve been using these coords for Balkans Theater. It may not be exact but it seems to work.
Min N 37 Max N 46
Min E 11 Max E 20 -

Min N 37 Max N 46
Min E 11 Max E 20I also found it to work nicely if the longitude and latitude differ 9°!
Enables me to use the local weather here! -
best way to judge the coordinates is to match winds and tempertures to the coastline. when looking in the Weather commander.
as grb2fmap will always convert the area it needs. it’s just a matter of matching if to the theater

GREAT tool Ahmed! THANKS! Well done!
Here’s a step by step Video tutorial for setting the weather using your tool
-
Great! Thank You very much Nikos.
-
Thanks a lot Ahmed! After 4.33 release, sure it’s the most important improvement for the environement. Easy to use and so pleasant! In a word : WONDERFULL

Thanks Nickos for the video! I’ll link to your post on my main post!

I can not download the file(GRIB).it is running.no response.Then the server is seem to ok(active).When I setup the time zone UTC +9.
The program stop.Any one have this problem.

I’m not seeing any inclement weather generated when I convert the GRIB to FMAP. The Zygrib data is showing precipitation but this is simply converting to poor weather for the FMAPS. Presumably there is some sort of precipitation value below which weather is poor and above which it’s inclement and I just haven’t downloaded any weather data to trigger inclement weather yet?
-
Yes, you need to satisfy both the minimum cloud cover and the minimum precipitation rate criteria. You can change those in the UI. Default values are 62.5% (5/8 BKN cloud) and 2mm/hr (‘moderate’ rainfall). You can lower them as you wish to move the bias towards more inclement weather (for Ex. try 0.01 precipitation rate as the other extreme).

Thank you

Thanks for your work!!
