jpeg compression not applyed after use of setmissval

Hi,

i have an uncompressed grib2 file that compresses ok with:

cdo -f grb2 -z jpeg -copy in.grb2 out.grb2

but setting the missing value with:

cdo -setmissval,-999.9 in.grb2 out.grb2
cdo -f grb2 -z jpeg copy out.grb2 outCompressed.grb2

cdo -f grb2 -z jpeg setmissval,-999.9 in.grb2 out.grb2

gives an output file without jpeg compression.

Using cdo 1.6.3 on linux.

Any hints or tips appreciated.

thanks,
Chris

Hi Chris,

GRIB2 jpeg compression in combination with missing values is not supported in CDO.
The next CDO release with will support this feature.
