Sentinel 3 atmospheric correction with iCOR ubuntu exception

snap iCOR

Hello everyone,

I am currently using SNAP 0.7 on Ubuntu 18.04 and iCOR-SENTINEL-3-OLCI and I am getting some error a few seconds after I start processing my L1-EFR image. This is the error stack:

Finished tool execution in 16 seconds

And this is the parameters file: iCORparams.xml (990 Bytes)

Any clues on why this is happening would be of great help.

Thanks in advance,
David

I have exactly the same problem. If anybody can help, I would appreciated.

Thank you in advance,

Finally I managed to find the solution with the aid of the following post:

There is a bug in the /opt/vito/icor/src/config/local_sentinel3_simec.ini in the Linux version of iCor. I replaced this file with the file that is available in the post above and the problem solved.

Kind Regards,
George
