Earthdata Forum

Hi,
I've downloaded Landsat 8 data from EarthExplorer Collection 2 Level 1: LC08_L1TP_015036_20230503_20230509_02_T1

I'm having difficulty processing it from l1a to l2 to get the estimated geophysical variables (OC suite) and eventual l3 binned product centered around Wilmington Cape Fear Estuary. Would you be able to provide some help with this process?

It will be helpful if you can describe the difficulty or share the error message.

Thanks for the prompt response. Apologies for not responding sooner. It's not an error message, its the resulting image that's the trouble. After processing with the l2gen, the chlor_a product looks like this (see attached screenshot). Very speckled, hardly any data there. It's not a cloud coverage issue, since the unprocessed image shows clear view of the land and Cape Fear Estuary system. Any suggestions for getting a better processed image with the OC suite products?

I tried l2gen on the same file, and got a different result.

I used V2023.2 and clicked "get_ancillary" before "run".

Ah I see, that is reassuring. Now if only I can figure out how to do the same. For the primary i/o files, which input file do i select in the Landsat file package?
