Title: Water quality in Lake Peipsi, Estonia, as seen by Sentinel-3's OLCI
Sentinel-3's OLCI surface reflectance on 14 June 2016 over Lake Peipsi in Estonia (left). Examples of water leaving reflectance products compared to in situ measurements indicating various water types (middle) and examples of water quality parameters derived from OLCI data (right).
Data showed bloom conditions, i.e. high concentration of Chlorophyll a (Point 1); area influenced by river inflow with high concentration of dissolved organic matter (Point 2), and higher amounts of total suspended matter and Chlorophyll a concentration towards the middle of the lake in comparison to more coastal areas (Point 3).
