Please let us know what version of SeaDAS and what tag of Science Processors (OCSSW) you are using? Or you can do SeaDAS-Toolbox -> Software & System Info and post the result here. Please also copy and paste the Landsat 8 L1 filename here, for it's hard to read the file name on the screenshot yo...

I am puzzled... I tried modis_GEO A2023164100000.L1A_LAC on MacOS 12.6.6 and linux Ubuntu 20.04.6 LTS, but could not replicate the error. Can you do modis_atteph A2023164100000.L1A_LAC getanc A2023164100000.L1A_LAC modis_atteph -s 2023164100000 -m aqua getanc -s 2023164100000 -m aqua and post the re...

Thanks for the clarification. Could you please do seadas_info and post the results here? When you did install_ocssw --install_dir $HOME/ocssw --tag V2023.2 --modisa you only updated modis and modisa files, but not seadas files and files of other sensors you have installed, such as modist. You might ...

The issue is that valid_min and valid_max for ipar are not defined in product.xml, and l2gen assigned 0 to valid_min and valid_max by default. We'll fix the issue for the next V tag. In the mean time, you can change valid_min and valid_max in product.xml, so l2gen will create L2 files with valid_min...

I have valid ipar data after running l2gen on A2023164100000.L1A_LAC. I noticed l2gen is defining the wrong "valid_max" attribute for ipar, both "valid_min = 0" and "valid_max = 0". I looked at ipar in ocssw/share/common/product.xml, but did not see "valid_max=0&qu...

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...
