Please let us know what version of SeaDAS you are using? SeaDAS 7 or 8? Please also let us know the name of one of modis L1A files that modis_GEO.py failed on. Here is another post regarding modis_GEO. The user has issues with modis L1A files on 2/11/2020. https://forum.earthdata.nasa.gov/viewtopic....

Try "--epixl=100", "--eline=100" as arguments

Actually, l2gen has no problems taking an SST file as icefile.

If you can share the name of your MSI S2A L1 file, we might be able to download the data from copernicus and help you further. The error you got is probably not due to the length of the file name. Another user got a similar error trying to do l2gen on S2A_MSIL1C_20160401T160029_N0201_R054_T17SQC_201...

Thanks for reporting the issue. We are investigating it.

I am a little puzzled why it's looking for OCSSW_bash.env.v7.5.3. It probably does not like --git-branch=v7.5.3.

Can you post here the result of ls -al /tmp ? Have you previously downloaded ocssw bundles in /tmp? If not, you should run ./install_ocssw.py --install-dir=/home/mmy/seadas-7.5.3/ocssw --git-branch=v7.5.3 --aqua –seawifs instead. I can't attach OCSSW_bash.env here, but here is the content of it: # #...

Try .

I am not sure about "--local=/tmp" part.

Can you do

You are welcome! l2gen version should show us your OCSSW tag. It's probably V2019.3 install_ocssw.py --list_tags should show you the available OCSSW tags, but the latest tag probably would not work with SeaDAS-7.5. Check out SeaDAS_8.2.0 -- https://seadas.gsfc.nasa.gov/downloads/. You can install Se...
