POC Algorithms

Hii What is the correlation between POC and Chl a? If I interpret that POC is a sub-product from Chl a, this means that Chl a (independent variable) and POC (dependent variable) are highly correlated (what I got and what is expected). However, when I change the analysis and put Chl a as dependent va...

PIC-Kd490 correlation

Hii :) I am analysing MODIS-Aqua derived OC and SST parameters for the Cape Verde region. I applied statistical analyses to see the correlation between some of these parameters and I realized that if I use Kd490 as independent variable and PIC as dependent variable (or vice versa), there is no signi...

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

Dear xuanyang02, I applied this algorithm in my thesis work. I would like to cite you for using this algorithm, so I would appreciate if you could tell me how to cite you properly in my Master thesis. Thank you so much :)

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?
