I’m kinda confused since there are level 1 and level 2 data of sentinel 3. I downloaded the free s3 l1c ol_efr from copernicus hub.
Does it mean that the data that i downloaded is only georefenced and has no radiometric calibration ?
So, i still need to do some preprocessing since I want to get the chl-a abd tsm by applying c2rcc?
I am new to snap and I’ve been searching for documentations and references. If you guys have something that can help me, please tell me. Thank you!
