CZCS bands to calculate FU index

by dion_rigatou » Wed Jul 19, 2023 11:54 am America/New_York

Dear ocean color team,
I want to use Rrs from CZCS sensor in order to extract Forel Ule index. However, I have found algorithms working with the bands from modern sensors (e.g., SeaWifs). Do you have any suggestions? Would it be acceptable to use the 5 bands from CZCS instead of the 6 bands that are available in the more recent sensors? Maybe you have other suggestion for this data transformation that can work with CZCS bands?
Thank you very much in advance.
Best regards,
Dionysia

Hi Dionysia,

As Forel-Ule Index is not one of our products, I cannot make comments on it. My suggestion is reviewing more literatures on this topic.

Uma,

Here is a help page about SNAP time series management:

Hope it helps.
