[THREDDS #MRV-895858]: $%#^@!%^#



Hi Roy,

I think Marcos was suggesting stacking all the GRIB records that use the 58-0-2 
table into one file and stacking all the GRIB records that use the 58-0-3 table 
into another file. The two resulting index files would each be self-consistent. 
Then doing a featureCollection to aggregate those two files might work because, 
we think, it is the inconsistency in the GRIB information rather than in the 
resulting netCDF information that causes trouble.

We haven't tried it out yet. But that might be a kludgy quick fix to try next.
