Tony,

OK.  If worst comes to worst, the raw grib messages are available.

>As far as 
>you know, its ready to ingest the data, right?

Right.

In the end, nothing was changed on your system.  This means that you will
not decode the ETA grids past H+48.  The MRF files should continue to
be decoded as they were.

After this blows over, we need to adjust your XCD decoding setup.  Quite
some time ago, the MRF stuff was split into MRF and AVN.  Your RTMODELS.CFG
file does not have an entry for AVN, and it should.

For reverence, our RTMODELS.CFG file now looks like:

# ...
#          ETA=  3 8001 120000 240000 480000
#          ETA=  3 7001 120000 240000 480000 GEO=211
#
# History: 20000403 - Changed ETA grid filing format (3 -> 1) in order to
#                       file grids out to 60 hours (March 29, 2000 NWS change)
#                     Moved start of NGM grids to 5501

SCRATCH=5001
ETA=  1 5011 120000 240000 480000
MRF=  1 5101 120000 240000 960000
MAPS= 0 5201 30000
MDR=  2 5301
AVN=  3 5401 120000 240000 720000
NGM=  3 5501 120000 240000 480000

I am saving all ETA grids in the GRID file range 5011 - 5070, and I am saving
the NGM grids starting at 5501.

>Thanks,

Later...
