John,

To my knowledge we have not used the RTMA data in MET.  But in reading
the document you sent, it looks like it's available in GRIB2 format.
Currently, MET can only handle GRIB version 1 data so
you'll need to run a simple reformatter to convert from GRIB2 back to
GRIB1 before using it in MET.  We use the "cnvgrib" tool here
(http://www.nco.ncep.noaa.gov/pmb/codes/GRIB2/) to convert between
GRIB2 and GRIB1.

Once you have the data in GRIB1 format, it should be very easy to use
in MET.

On a side note, MET will be enhanced to support GRIB2 in the next year
or so, but for the time being, you're stuck with having to reformat
it.

Hope that answers your questions.
