Hi Massoud,

The 12 km NAM products are in the CONDUIT datastream.  SPARE
is used for mostly non-"operational" (i.e., test) feeds.

Are you referring to the objective region of interest technique that Steve 
Chiswell
uses to locate mesoscale model runs (examples on our web page)?  If yes, then
I believe that Steve is using precipitation fields from one of the IDD 
datastreams
that you already talked about ingesting: HDS, NGRID, CONDUIT.

By the way, Steve presented an AMS paper on his ROI technique a couple of years 
back:

If your LDM is setup like we had been talking about in other emails, then you
should already be ingesting the data necessary to identify regions of
interest.  If you have specific questions on how Steve is calculating his
regions of interest, you should send your questions to address@hidden.

GEMPAK's NMAP

Steve is the best source for answering your questions on how he is identifying
regions of interest and then using them to identify the center point of the
domain in a mesoscale model (e.g., ETA or WRF) run.  Again, send those questions
to address@hidden.

Cheers,

Tom
