19990315: Quick question

Steve,

In December, Unidata switched the IDD feed from FOS to
NOAAport. On NOAAport, there are several NGM, ETA, MRF and
AVN projections.

In terms of retreiving NGM grids for such a long period, I suspect
that the typical places such as Illinois and Washington would
be swamped. I know NCAR SCD was keeping 30 days online and
archiving the rest. Perhaps this is something that this
data archive project would be appropriate. You might want to ask Ben
Domenico or Dave Fulker as to how to proceed on that end since
I don't know exactly where they are in this regard.

Chiz

here are the annotated pqact.conf entries I provided. The
projection number is referenced with the 3rd character in the
WMO name. I updated dcgrib last year to use @@@ as a template
to store data by the grid id number so that a single pqact.conf
line could handle many projections
