Matt, dcgrib and dcgrib2 are used to convert GRIB into GEMPAK. There is a program called gdgrib that can produce a grib product from a GEMPAK grid parameter. See the online help for using gdgrib including specifying the PDS paramaters will define the product. The process of creating a grib is by running the program for each parameter/level that you want converted.
