In plain English

What it measures. The carefully calibrated version of ocean color and water-leaving reflectance at 300-meter detail, signaling water clarity and phytoplankton.

How it's made. Made by ESA Copernicus from the Sentinel-3 Ocean and Land Color Instrument as non-time-critical Level-2 water products.
