Re: PIC Algorithms

Thank you so much because this is a doubt we had for some time! If I may ask you one more question: what about the PFT (phytoplankton functional type) products? Does this mean what you said is taken into consideration for deriving the PFT products? And also, I should interpret the chl a product does...

Re: PIC Algorithms

Thank you so much! This is now a lot more enlightening to me. But I still have a doubt: on my data whenever I have high values of PIC, usually they are associated with low values of chlorophyll a. I see that in different regions of the oceans, namely Azores and Cape Verde, for example. So, shouldn't...

Re: How to average images with clouds and ignore these cloud pixels?

I used the expression you gave and I got a full white image with NaN pixels. Should I do chlor_a < 0 instead of chlor_a > 0?

Re: How to average images with clouds and ignore these cloud pixels?

Hii! Thank you for your answer.

Actually, I was using the Math Band tool to put the files together. I tried with the Collocation Tool and it gave me a java error...

Is it possible to use the example expression for the Math Band Tool without using the Collocation Tool?

How to average images with clouds and ignore these cloud pixels?

Hello everyone, I am trying to get a monthly climate mean using 20 years of, for example, January month. My problem is that out of the 20 imagery I have 15 that have a lot of clouds. When I averaged them in SeaDAS I got negative values almost everywhere which means the cloud pixels are being taken i...

PIC Algorithms

Hello everyone, Usually PIC algorithms are related with coccolitophores. However, some species of zooplankton also incorporate CaCO3 in their skeleton so how can we be sure that the concentrations and/or variability of PIC that we observe in the satellite imagery (MODIS) reflect only phytoplankton (...
