PACE l2gen

by ana_dogliotti » Tue May 07, 2024 4:55 pm America/New_York

Hi,

I installed seadas 9.0 (Ubuntu 22.04), Tag T2024.16, python 3.11

I'm trying to process OCI L1B data and the log file starts

execution exception: java.io.IOException: l2gen failed with exit code 139.
...
and ends with

/home/tele/SeaDAS/ocssw/bin/ocssw_runner: line 23: 6912 Segmentation fault (core dumped) $*

This is my par file
aer_opt=-1
aer_wave_long=1618
aer_wave_short=1250
brdf_opt=0
cloud_thresh=0.018
cloud_wave=2130.0

Thanks

Right now the only aerosol option that works with OCI is

aer_opt=-18

I will look into why l2gen is seg faulting. Not nice.

If I set aer_opt=-18

l2gen fails with:
/home/dshea/ocssw/src/l2gen/atmocor2.c line 217: the first mbac wavelength 751 shouldn't be shorter than aer_wave_short 1250

If I replace:
aer_waer_wave_short=1250
aer_wave_long=1618

with:
aer_wave_short=751
aer_wave_long=870

l2gen completes without error.
I also noted that your output file name does not match your input file name.
While not the cause of an error, it could cause some confusion
