Right.  On July 1, we discontinued the non-image products from the
Unidata-Wisconsin (LDM feed type MCIDAS) datastream.

This is when the non-image products stopped being sent in the Unidata-Wisconsin
datastream.  Julian day 99182 is July 1 (you can use the McIDAS routine
DATELIST to do these sorts of interpretations).

The replacements files for these are created by the XCD decoders.  The
advantage of using XCD is that instead of having surface and upper air
data for only North America (and occasionally not including down to
Puerto Rico), you get global coverage.  The same is true for the GRIDs.
All of the model output in NOAAPORT is being carried by the Unidata IDD
and is decodable by XCD decoders into McIDAS GRID products.  Decoding
all fo the data requires a substantial amount of disk space, so be careful
to check disk space before turning this on AND make sure that you are
scouring the files correctly (using mcscour.sh as per the web based
McIDAS installation/configuration instructions.

So, if you havn't setup XCD (I thought that you had), you need to do so

The Mollweide Composite imagery is not the same as the GOES-8 (now GOES-East)
North America data.  The Mollweide Composite is sent in the Unidata-Wisconsin
datastream as product UY as you have noted.  The GOES-8 North America H2O
data comes in the product UW.

Hmm...  You say that the routing table indicates that you are receiving
the data.  If you are and they are being decoded, then you should be able
do check for their existence by doing things like:

LA 110 119
DF 110 1

We need to find out if the images are being properly decoded.  If they
are, we then need to find out why the ALOOP command being run by the
7.5 Fkey menu is not displaying them.  The first steps are those listed
above.  Please run the commands from a McIDAS-X session and report the
output back so I can take a look.
