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.

Thank you for your prompt reply.

Dear Sir,
I am also looking for the Forel-Ule index, Could you suggest any Seadas/SNAP tool for long time data analysis ?? any help on it


Thanks and Regards
Uma
