When you bin all the files like AQUA_MODIS.20190101T002000.L2.OC.nc on the day 20190101 by the product chlor_a, you get AQUA_ MODIS.20190101.L3b.DAY.CHL.nc

When you map the AQUA_ MODIS.20190101.L3b.DAY.CHL.nc file, you get AQUA_ MODIS.20190101.L3m.DAY.CHL.nc, which could be visualized by SeaDAS

I processed A2024364200500.L1A_LAC to L1B without any error. The tag I used is V2024.8

I did modis_GEO on A2024300194500.L1A_LAC, and modis_L1B was successful too. I am using SeaDAS 9.1.0, OCSSW is V2024.8.

The latest version of SeaDAS is 9.1.0, and we no longer support SeaDAS 7. If you are a college student looking to use SeaDAS 9 to analyze and process remote sensing data, a Mac laptop is recommended.

Could you please share the name of your file, so we can replicate the issue?

Please let us know what version of SeaDAS are you using.

It will be helpful for us to replicate the issues if you can share the name of the Landsat L8 and l9 files, and from where you downloaded the files.

If you can use SANP GPT, you should be able to use SeaDAS GPT, for SeaDAS is built on SNAP
