Creating GRIB1 and GRIB2 Files with DMBIN

When the unpacking process is complete and the entire GRIB message is successfully decoded, the decoder passes the GRIB structures to DMBIN, which stores metadata about the GRIB messages in the MySQL database. DMBIN also writes raw GRIB1, GRIB2, and BUFR data to files to which the database points. DMBIN does not use the RTMODELS.CFG file.

Once the correct GRIB1 or GRIB2 file is determined, DMBIN files the metadata in the database as is. It is up to the GRIB server to determine if the grid must be pieced together with other corresponding grids of the same field, time, etc. Piecing together is often necessary because most of the gridded fields that cover the globe are sent in four or eight pieces, as in the GFS-GLME dataset.
