V2024.1 modis sst processing (l2gen failed)

[oo_processing]

Dear Support,

I installed the V2024.1, modis sst processing failed, but which was successful with V2024.0; moreover, removing sst options, the l2gen ran successfully.
the following l2gen error message is for your info, the SSES LUT files are same between V2024.0 and V2024.1 (compared by the diff command)

Are you fully updated to V2024.1?

cat SeaDAS/ocssw/share/modis/msl12_defaults.par

You should see these lines:

# algorithm controls
# ------------------
btfile=$OCDATAROOT/modis/aqua/cal/bt_modisa.hdf

Make that:

Thanks Tommy,

Adding those 3 lines make it work. There are two par files to modify
$OCDATAROOT/modis/aqua/msl12_defaults.par
$OCDATAROOT/modis/terra/msl12_defaults.par

Review my installation steps, I compiled the binary files and using the following command to install the par files.
$ install_V2024.1/install_ocssw --install_dir ./V2024.1 --tag V2024.1 --oci --modisa --modist
I did it again in a different install_dir, and the modisa/t par files are still missing those 3 lines. So, I think the install program needs to be fixed.

Best

Yes, there is a SeaDAS patch to address this in the works.
I don't know if it will be an update to V2024.1 or a new tag.
