Data Representation Template 5.40 is (Grid Point Data - JPEG2000 Compression) (Lossless)<br>
My build of the grib2c library is linked with a build of jasper that supports jpeg2000, so it works for me (see attached). If rebuilding your grib2 library is not an option, I believe you can use wgrib2 to rewrite the grib2 records and change the DRT to a different compression setting. ?Jennifer<br>
