Operational MRMS GRIB2 Tables

NOTE: All GRIB2 MRMS product filenames have "MRMS_" prepended. For example, "ReflectivityAtLowestAltitude" is actually "MRMS_ReflectivityAtLowestAltitude".

Below is an example filename pattern for MRMS data:

/nfsdata/realtime/outgoing/grib2/MRMS_ReflectivityAtLowestAltitude_00.50_20150212-183408.grib2.gz

where "00.50" is the height of the field in kilometers and "20150212-183408" is the UTC time stamp [year][month][day]-[hour][minute][second]
