In order to be able to interpolate GRIB-2 fields, users must upgrade to latest version of EMOSLIB which offers an solution for the interpolation both GRIB-1 and GRIB-2 data by using the grib_api library.

Please note:

Respectilvely , INTUVP2 is routine for generating U and V wind components from vorticity and divergence fields for GRIB-1 and GRIB-2 data
