Re: ARTIFACTS IN L3 MODIS ACQUA CHLOROPHYLL IMAGES

Hi, sorry for the delayed response. And sorry that I can't debug your code, but have you noticed similar patterns in our L3 MODIS Aqua chlorophyll images? If so, please provide more details. Otherwise, you may want to check your code for the way that you count the NAN at the same pixel/bin/location.

Re: CZCS bands to calculate FU index

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.
