[ldmMcidas #XGX-360555]: decoding FNEXRAD 1 km N0R composite images

["Unidata ldm-mcidas Support" <support-ldm-mcidas@xxxxxxxxxxxxxxxx>]

Hi Elmer,

Just to be clear: the directory structure I proposed is not needed; it is
desirable.

The product you are decoding _is_ a national composite of NEXRAD Level III
base reflectivity at the lowest radar tilt.  The pngg2gini outout you sent
previously:

demonstrates this since only the 1 km N0R composite will uncompress
to a size of 14 MB.

That product is a national composite sent out as a GRIB message.

It is not.  You already are already ingesting and apparently processing
the correct product.

Cheers,
