Decompression disabled, szlib not available!

[ackerlar]

Hi all,
I want to process echam output with CDO on levante and get this error:

Decompression disabled, szlib not available!
Error (grbUnzipRecord): Decompression problem!

E.g. for this file: /work/ba0989/a270124/PalModII/experiments/icb_sh_ctl/outdata/echam/icb_sh_ctl_208601.01_accw

Does anybody know if there is a way to come around this error?

Hi Lars,

Did you load the cdo module? This works fine on Levante:

#!/bin/bash -e

module load cdo
echo "Using cdo $(cdo --version)"
cdo -t echam6 info icb_sh_ctl_208601.01_accw
cdo -f nc -t echam6 fldmean icb_sh_ctl_208601.01_accw icb_sh_ctl_208601.01_accw_fldmean.nc

Output:

You can see my test script here:

/work/ab0246/a270077/SciComp/User_Support/a270124/cdo_example.sh

Does that help with your problem?

Thank you! Yes, this works for me, too.
