Operational MRMS GRIB2 Tables

This information is current for MRMS Version 12.2.

NOTE: Downloadable User and Flag Tables have been moved to Github: https://github.com/NOAA-National-Severe-Storms-Laboratory/mrms-support (18 July 2024)

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/CONUS/MRMS_ReflectivityAtLowestAltitude_00.50_20201012-183805.grib2.gz

where "00.50" is the height of the field in kilometers and "20201012-183805" is the UTC time stamp [year][month][day]-[hour][minute][second]
