20060330: NMQ data feed

Ken,

The LDM feed is working well. 
We have the feed request set up and I have modified my software for the 
changes in NetCDF files for the new products from what had been available 
previously.
One issue I noticed is that the missing data value has been scaled just as all 
the other data
values, which means that I have to unscale all the data values, rather than 
just valid data values.
Eg, missing data in the 2D files are -9990f in the CREF, while the attributes 
provide than
SCALE=10 and missing is -999f.

I do plan on looking at stitching together the tiles in some way and packing 
into
either GRIB2 or a compressed image format, since it is somewhat awkward to have 
635MB 
over 8 tile files for a 2D composite reflectivity plot (I estimated it would be 
23GB for a 3 hour loop).


Thanks for checking in,

Steve Chiswell
