L2gen does not work on landsat 9 L1B files yet. We are implementing it and it will hopefully be in the next tag of OCSSW.

If you have another copy of python3 in /usr/local/bin/, it might be easier to point SeaDAS to use that copy of python3 by adding this line export PATH="/usr/local/bin/python3:$PATH" to your bash file. If you still want to use /opt/anaconda3/bin/python3, you can refer to this post to set th...

The latest R tag is R2022.4. You can install it with SeaDAS 8.2.0. https://seadas.gsfc.nasa.gov/downloads/

As we reprocess more missions, we'll add more tags like R2022.5, R2022.6...

True, modis_atteph.py does not have knowledge of failed pixel geolocation. It looks at the L1 file to determine the scene start and stop time which it then uses to select and download the correct ancillary data.

l2gen takes L1B and geo files as input. See https://seadas.gsfc.nasa.gov/help-8.2.0/processors/ProcessL2gen.html#COMMAND_LINE_HELP

It seems that l2gen can't find the geo file that goes with your L1B file. It might be helpful that you share the command line or the par file for l2gen.

It seems that your SeaDAS is using /opt/anaconda3/bin/python3, you might need to Here is another post discussing requests for anaconda viewtopic.php?t=2198&sid=ea8d28dd2d6e7039161626549686fe33&start=30

Sure, we will notify you once the new API and script work as expected.

Meanwhile, you can still use the V2021.2 or earlier OCSSW

Atmospheric correction is relevant for SST.

Can you do SeaDAS-OCSSW -> SeaDAS/System Info and post the results here?

It probably has something to do with your environment.
