Re: L2gen output missing OLCI bands >709 nm

Use Rrs_nnn instead of Rrs_vvv as in "Kd_490 Rrs_nnn angstrom aot_865 chlor_a" for l2prod in the Selected Products tab.

I used V2023.3 for the Science Processors (OCSSW)

If you are using SeaDAS 8.4.0, I believe the right command is find_matchup and make_matchup. Here are the help pages -- https://seadas.gsfc.nasa.gov/help-8.4.0/FieldMeasurements/FindMatchups.html https://seadas.gsfc.nasa.gov/help-8.4.0/FieldMeasurements/MakeMatchups.html Could you please try /Users/...

Re: how to use code to run l2gen correctly

L2 needs an L1B file + GEO file as input If /Users/sawyerduan/Downloads/vim is a list of L1B files, they have to follow the OBPG File Naming Convention https://oceancolor.gsfc.nasa.gov/resources/docs/filenaming-convention/, such as AQUA_MODIS.20231014T060500.L1B.hdf, with the corresponding GEO file ...

Re: how to use code to run l2gen correctly

Can you do

Code: Select all

seadas_info
and share the result here?

Is your Mac with M1/M2 chip? If so, you need take extra steps to set up the environment in order to run l2gen https://seadas.gsfc.nasa.gov/downloads/

Or you can try to run l2gen using Client Server model (docker is recommended)
