20010222: Information on GRIB process/model identifiers

Brian,

These are QPE and NWW3 related grids. The NWS (center 8) process 0 is the RCM 
grid (HAXA00 KWBC).
Some of the River Forecast Center QPF (Center=9) gribs now use the subcenter 
(PDS 26) to identify the NWS
office.  I have most of them defined in the $GEMTBL/grid/gribkey.tbl
file that dcgrib2 will use for automatically naming the data files. I'll attatch
below if you aren't using GEMPAK and/or dcgrib2. In general, I just pipe the 
entire
set of grib headers to one dcgrib2 invocation and let the table define the file 
name,
nnumber of grids etc- instead of trying to maintain a separate set of 
pqact.conf entries.

!center subcenter modelid grid   Output grid file name
