Re: PIC Algorithms
By the way, here is the OBDAAC page on the PIC algorithm, if you have not seen it earlier.

Re: PIC Algorithms
At this point you have gone beyond my basic understanding of the PIC algorithm, so I would recommend further correspondence with the OBDAAC staff. I will add the "OBDAAC" tag to this thread. It is my expectation that the chl-a product does not provide a good estimate of chlorophyll in Ehux.

Re: PIC Algorithms
That's a good question. As I recall, the high reflectivity of the coccolithophores makes it difficult to properly estimate chlorophyll in cocco blooms. I think (though I can be corrected) that chl-a processing includes a coccolithophore bloom mask because of that interference. I.e., so much light is...

Re: Regarding bins in MERRA
Regarding your question, can you provide a MERRA-2 document or web page where the term "bin" is used? Bin commonly refers to a data storage location in which all valid observations for a particular spatial resolution are kept, until averaging over a time period is performed to provide a va...
