For example, in GRIB1, there is a paramId for Volumetric soil water layer 1 and a different paramId for Volumetric soil water layer 2, etc. In GRIB2, only a single paramId is used for Volumetric soil water, with the layer 1 having level=1 and layer 2 having level=2.

These parameters will be archived in MARS with levtype=sol (surface other levels). To retrieve these parameters in GRIB2, users will need to change their MARS requests to specify levtype=sol,levelist=1/2/3/4.
