Thanks, Tom, I'll check that out.

Hi Robert,

 

It's not exactly what you're looking for, but might do in a pinch. 

 

The LEAD project maintains a multi-month archive of many datasets including
a bunch of the NCEP model datasets found.  The top level catalog is found
at: http://lead.unidata.ucar.edu:8080/thredds/catalog.html

 

Part of that is the 211 grid GFS.  The sub-catalog is found at:
http://lead.unidata.ucar.edu:8080/thredds/catalog/model/NCEP/GFS/CONUS_80km/
catalog.html

 

I hope this helps.

 

Tom.

Kevin,

Thanks, but it's the GFS I am looking for, not the NAM.

Thanks,
Robert

Robert...

On ftpprd.ncep.noaa.gov, go to /pub/data/nccf/com/nam/prod/nam.20080522.
Substitute the correct date.  GRIB2 files of the NAM 40km look like:

nam.t##z.awip3d##.tm00.grib2

The first ## are the runs, as in 00, 06, 12, and 18.  The second ## are the
times into the forecast, as in 00, 03, ..., 84.

The are the same size as the files that via LDM, though I suspect the order
of the individual records are different.
