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:
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.
