David;

I understand your problem, but the only way for our systems
folks to test the backup 'in its entirety' is to do these
darned quarterly tests.  I am looking into a way to get the
grid 104 GRBGRD files made from the AFWA backup run but that
processing is done in Silver Spring - not at NCEP.

Linda and Geoff,

Our real-time MM5 simulations suffer significant delays every time one
of these backup tests occur.  In the end, I have to use a completely
different model to initialize our forecasts.  I have just checked the
referenced web site, but I cannot now determine, nor have I been able
in the past to determine, how to retrieve the proper backup grids.

We use the ETA 104 grids for our forecasts and we look at the
NMC2/CONDUIT feed and on tgftp.nws.noaa.gov in:
 /SL.us008001/ST.opnl/MT.eta_CY.12/RD.20020123/PT.grid_DF.gr1/
with files:
   fh.0000_tl.press_gr.grbgrd
through
   fh.0060_tl.press_gr.grbgrd

If either of you can point me to where backup ETA 104 grids produced
by AFWA can be found, that would be very helpful.

Sincerely,

David
