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

This is in my par file -- ifile=/Users/*/Scenes/SGLI/forum/GC1SG1_202205260207P05515_1BSG_VNRDK_2005.h5 l2prod="Kd_490 Rrs_vvv angstrom aot_867 chlor_a glint_coef rhos_1385 rhos_490 rhos_566 rhos_672 rhos_867 chl_ocx" ofile=/Users/*/Scenes/SGLI/forum/GC1_SGLI.20220526T020721.L2.OC.nc Yes, ...

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.

Strange, I did l2gen on GC1SG1_202205260207P05515_1BSN_VNRDK_2005.h5 with l2prod=rhos_490 rhos_566 rhos_672 rhos_867 rhos_1385 glint_coef chlor_a, and this is the image of rhos_1385

What exactly is in your par file? What tag of OCSSW are you using?

At this moment, l2gen cannot take subset options (north= south= east= west=) with resolution=250 or 500. If your ordered data is already extracted, you can just omit the subset options for l2gen. Otherwise, you need to do l1aextract_modis on the L1A files and create corresponding geo and L1B files a...

Sorry for the inconvenience. We are working on the new API and the script that uses the new API so modis_atteph will return the status as follows:

0 - all is well in the world
1 - predicted attitude selected
2 - predicted ephemeris selected
4 - no attitude found
8 - no ephemeris found
