VIIRS l2gen error in initialization
Posted: Thu Feb 03, 2022 1:30 pm America/New_York
When I'm processing a VIIRS SNPP file with l2gen I'm getting various errors. Any thoughts? See printout from l2gen below and the contents of the par file used as input.
I upgraded my ocssw code to V2021.2 last week. I download both the L1A and GEO files from the direct data access links.
