It appears that there is something wrong with the calibrating of the
NEXRCOMP images that are being created from GRIB messages that Chiz is
making.  As you note, the units for N0R products should be consistent
across the board.

This unit is incorrect in the same way that the WATR unit for the other
NEXRCOMP images.

Since the calibrations used to be correct (I checked these
extensively), there must have been a change on motherlode that is
causing the problems (maybe something got stomped on during the
recent disk fill episode).  My first guess would be that the GRIB
table/table entry is being used incorrectly by GRIB2IMG.

I will investigate and take corrective actions.
