How MODIS processed climatology data

[nabilanona]

I want to use the monthly climatology data of chlorophyll-a concentration from MODIS Level 3 database, is there a document that explain how this data calculated? thank you

Are you asking how the means are calculated or how chlorophyll-a concentration is calculated?

The mean values are the arithmetic mean of all of the monthly means for that particular month for the entire mission.

The algorithm we use is described here : Chlorophyll a (chlor_a; mg m-3)

Yes, I am asking about how the means are calculated. How about the outliers data? Are the outliers data removed from the arithmatical calculation?

Thank you,

No - they are not trimmed in any way.
