Temporal changes in the remote sensing reflectance at Lake Vänern
The Aerosol Robotic Network - Ocean Color (AERONET-OC) instrument located at the Pålgrunden site in Lake Vänern provides values of remote sensing reflectance RRS(λ) since 2008. These in situ RRS(λ) indicated a temporal increase from 2015. To investigate the environmental and climate processes respon...
