Hi,

we’re using the netcdf-library to read ECMWF grib files.
Model level data is delivered in Grib-2-Format.
Some of those files throw an exception when loaded with netcdf-lib stating 
"Unsupported DRS type = 50002“.

DRS is Data Representation Section, is it? …some compression method missing? 

(Can send example file if needed…)
