[LDM #VBU-998349]: MRMS data request

Sebastien,

GRIB is a message-based format, so you can take multiple grib files and just 
concatenate them. From unix, you could do this as:

cat MRMS*.grib2 > my_new_grib_file.grib2

You could then use GRIB-aware tools, like pygrib or netCDF-java to open the 
tools and they should give you the data as the 3D cube you're looking for.

Keep in mind we're not responsible for MRMS, we only distribute what's sent out 
over NOAAPORT, so we have no control over the format and what's available.
