nomads gfs file changes pgrb2 data help

Post by theocarter2911 » Thu Jun 13, 2019 2:40 am

Hi All,

I use a script that I got from another user here long ago which downloads and combines gfs pgrb2 and pgrb2b files over a limited area for the office so that we have a full gfs for 120 hours to use for the region (not full global) that has limited file size for quick and easier downloads.

From yesterday due to the changes to gfs on the nomads servers it is broken, I am guessing due to a change in file name or file location?

Mine used to look like this: (the brackets around https is so it shows text instead of a link here)

(https://)nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl?file=gfs.t00z.pgrb2.0p25.f216&all_lev=on&all_var=on&&subregion=&leftlon=30.00&rightlon=75.00&toplat=40&bottomlat=10.00&dir=%2Fgfs.2019061300

and

(https://)nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25b.pl?file=gfs.t00z.pgrb2b.0p25.f216&all_lev=on&all_var=on&&subregion=&leftlon=30.00&rightlon=75.00&toplat=40&bottomlat=10.00&dir=%2Fgfs.2019061300

.....for the pgrb2 and pgrb2b files - then the two get added together to make a "full" gfs file for the forecast hour.

Does anybody know what the new file name or location would be that is comparable?

Best regards,
Theo

Found the change! In DATADIR the forecast run datetime and cc (start of run time) example 2019061300 becomes 20190613/00. Just have to add in the slash in the runscript.
