Chlorophyll High Resolution


The surface chlorophyll-a concentration, a pigment which is present in the phytoplankton cells, is measured by satellite optical radiometers (passive remote sensing). Chlorophyll-a concentration is a proxy for the surface primary productivity, but represents only the surface concentration.
The product is a 5-day average, high resolution, which is a simple data average of the satellite measurements (optical radiometers) taken over the 5 previous days (giving more weight to the most recent data). The processing takes into account input data at level 1A.

This product may locally be highly gappy due to the presence of clouds or missing data.
