Hello!

I got S-3 images, and I need to monitor CHL-a in Bali strait using CHL_NN image and OC4Me image, but I don’t understand what to do with it.
Is there anybody who understands how to pre-process or process the OLCI Level-2 Images? since I’ve read that we don’t need to do any correction with CHL_NN image and OC4Me image.

Thank you…

You can directly use the values of CHL_OC4ME and CHL_NN both give you chl-a. You need to judge, which one gives better results for your area. For example by comparing with in-situ data.

so we don’t need to do any corrections, right? and fortunately, I have the in-situ data.
thanks again:)
