Segmentation fault in MODIS iop_opts=2 GSM

by aliolive » Thu Mar 31, 2022 1:56 pm America/New_York

I am trying to process MODIS imagery from L1A to L3 but I have been facing some issues.
I am currently using a LINUX machine with Seadas 8.1.
I am testing the A2021098160000.nc scene.
Lat1 -20 Lat2 -30
Lon1-39 Lon2-49
In the l2gen processing settings
When I choose the gsm products (e.g., bbp_vvv_gsm), set the IOP Options as iop_opt=2 (GSM) and set the rest of the parameters as default.
The following error comes out

Applying ocean BRDF including:
Reflection/refraction for upwelling radiance.
Reflection/refraction for downwelling radiance.
Morel f/Q

No Raman scattering correction calculated for Rrs.

Loading Raman coefficients from: /opt/seadas-8.1/ocssw/share/modis/aqua/raman.nc.
/opt/seadas-8.1/ocssw/bin/ocssw_runner, row 23: 2953085 Segmentation Fault $*

Any idea how to solve this?
Thank you!

Are you using OCSSW V2021.2?

Make sure GSM is chosen for Suite on l2gen's Main tab

No, it is V2022.0.

Did l2gen work when you chose GSM for Suite on l2gen's main tab?

The selection of the Suite =GSM works, however, differently from the SUITE=IOP(which selects automatically opt_iop=7(GIOP)) it does not select the opt_iop=2(GSM) in the IOP options tab. And when I select it before running the code, an error occurs in the processing.
