Robert,
This data is also part of what we are distributing in the NMC2 model
data feed of high resolution data (1 degree global grids, 3 hourly
forecast periods out to 78 hours, about 650 MB per run).
To decode the data (via ftp or the LDM into gempak), cat or pipe
the data to dcgrib.
cat avn_gribfile | dcgrib PACK YYMMDDHH_avn_grid@@@.gem
For more information on the CONDUIT project where we are providing an
IDD feed of some of the OSO ftp server products, see:
