Standard MODIS Aqua Ocean Color products were found to not provide a suitable calibration for high altitude lakes such as the Lake Tanganyika . Our results show that for the geographical, atmospheric and optical conditions of Lake Tanganyika : (i) a coastal aerosol model set with high relative humidity (90%) provides a suitable atmospheric correction;

Lake Tanganyika is one of the world s great freshwater ecosystems. In recent decades its hydrodynamic characteristics have undergone important changes that have had consequences on the lake s primary productivity. The establishment of a long-term Ocean Color dataset for Lake Tanganyika is a fundamental tool for understanding and monitoring these changes.
