Re: Threshold Definition

Hello,

Thank you for your answer. I just wanted to clarify if the Kd490 and Chl a algorithms are also mainly for open ocean/case-1 waters.

Once again, thank you for your time!

Threshold Definition

Hi everyone, Currently, I am working with monthly statistics derived from L2map MODIS-Aqua satellite parameters. When conducting a monthly statistical analysis on the maximum values in the Cape Verde region, specifically POC, I found that around 70% of the registered values align with the maximum th...

Arithmetic Mean 3x3 SeaDAS

Hi everyone, I am currently processing MODIS-Aqua images through SeaDAS software but have noted that upon applying the 3x3 Arithmetic Filter, certain ocean pixels from the original images are now identified as land pixels, specifically near the coast. Can you please elaborate on the functioning of t...

Chlorophyll-a algorithm & sediment contamination

Hii everyone, I am analysing spatial patterns around an island in Cape Verde using MODIS-Aqua L2map satellite images. I have detected unusually high Chlor-a pixel values in the coastal regions compared to the rest of the image. This abnormality typically occurs in about 12 pixels out of the entire i...

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: 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...
