There is probably something wrong with ocssw/var/log/ancillary_data.db. You can run modis_atteph -r A2023164010000.L1A_LAC That'll download the att1/eph1 file. Then modis_GEO would work. Also, MODIS TERRA GEO file is available for download here -- https://oceandata.sci.gsfc.nasa.gov/directdataaccess...

What product name did you use for "chlor_a"? The default products for Landsat 8 are "Kd_490 Rrs_vvv angstrom aot_865 chlor_a". Make sure it's "chlor_a" with an underscore. Can you take a screenshot of your l2gen GUI "Products" tab, and post it here? Can you al...

I got the same error you got -- /Users/dshea/ocssw/oel_util/libpiutils/productInfo.cpp Line 948: need a default chlorophyll algorithm for this sensor running $ ~/ocssw/bin/ocssw_runner --ocsswroot ~/ocssw ~/ocssw/bin/l2gen suite=OC ifile=JPSS2_VIIRS.20230608T110600.L1A.nc geofile=JPSS2_VIIRS.2023060...

Unfortunately, I can't replicate your error. Can you update OCSSW to V2023.2? However, l2gen will complain that it can't open $OCVARROOT/viirsj2/cal/OPER/VIIRS_J2_CAL_STATIC_LUT_v3.2.3.1_20221202_vcst.nc and $OCVARROOT/viirsj2/cal/OPER/VIIRS_J2_CAL_RSB_DYNAMIC_LUT_20221129_20230430_v3.2.3.2_20230216...

For GOCI, you can download L1B files here -- https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-1B/GOCI or here -- https://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=amod And you can do l2gen (SeaDAS processor) on GOCI L1B files with product sena (satellite azimuth angle) and senz (satellite...

Please do SeaDAS-Toolbox -> Software & System Info and post the output here.

Please also share the name of your JPSS2 L1 File, and I assume that you provided a corresponding GEO file

It's always nice to be acknowledged

Here is the link to "how to cite" -- https://oceancolor.gsfc.nasa.gov/resources/how-to-cite/

It turns out that the metadata information in LANDSAT 8/9 OLI files that start with "LO" have changed, so obpg_file_type returns "OLI: Level 1B " instead of "OLI L8: Level 1B". That is causing the problem. $ obpg_file_type LO08_L1TP_130044_20230423_20230425_02_T1/LO08_L...

You might need to close SeaDAS, delete .seadas8 directory and restart SeaDAS. Edit seadas.properties again. When you open l2gen, it'll open SeaDAS Processors Location window, and it's ok to choose Virtual Machine for "OCSSW Location". Here is the link to the webinar "Learn How to Use ...

Can you do SeaDAS-Toolbox -> Software & System Info, and post the output here?

Also, can you do Is LO09_L1TP_131044_20220318_20230424_02_T1_MTL.txt a Landsat L9 file? Do you have olil9 mission installed?
