hi arlindo, please see: ftp://ftp.nhc.noaa.gov/users/fiorino/model.tar for a sample of 0.5 deg gfs data for tau=0,24,48,72 from today's gfs run (2008021312) and for 850,500,200 -rw-r--r-- mfiorino/users 592 2008-02-13 23:45:37 model1.ctl -rw-r--r-- mfiorino/users 1705 2008-02-13 23:45:48 model1.gmp1 -rwxr-xr-x mfiorino/users 6174444 2008-02-13 23:35:49 model.f000.grb1 -rw-r--r-- mfiorino/users 2176111 2008-02-13 23:35:40 model.f000.grb2 -rwxr-xr-x mfiorino/users 6401958 2008-02-13 23:36:04 model.f024.grb1 -rw-r--r-- mfiorino/users 2115250 2008-02-13 23:35:55 model.f024.grb2 -rwxr-xr-x mfiorino/users 6531918 2008-02-13 23:36:18 model.f048.grb1 -rw-r--r-- mfiorino/users 2319105 2008-02-13 23:36:09 model.f048.grb2 -rwxr-xr-x mfiorino/users 6531918 2008-02-13 23:36:33 model.f072.grb1 -rw-r--r-- mfiorino/users 2295825 2008-02-13 23:36:24 model.f072.grb2 the .grb2 data comes off the operational file system so is as "ncep" as you get... i used convgrb to convert to grib2 (.grb1) and the model1.ctl works against the .grb1 data. these files are a lot beefier than the original model.grb, but then so are the models.. let me know if you need more/less fields, i have a pretty slick python script that uses wgrib2 to inventory and extract out specific fields... best /r mike Arlindo da Silva wrote: > All, > > I just downloaded Jennifer's latest sources, merged with my > previous patches, and checked back in our repo.
