data aggregation method?

For MODIS Aqua data, specifically MODIS Chlorophyll-a Concentration Level 3, that are aggregated beyond daily values, how are the aggregated data grouped? Wondering if they are mean, median, etc. I am unable to find this in the documentation.

The binning uses a naive mean for aggregating spatially and temporally. While it is old, the original documentation for the binner is still (mostly) valid: https://oceancolor.gsfc.nasa.gov/resources/docs/technical/seawifs_reports/prelaunch/vol32_abs/

(e.g. ignore anything mentioning maximum likelihood estimator :D )
