Assessment of Atmospheric Correction Methods for Sentinel-2 MSI Images Applied to Chlorophyll-A Retrieval in an Eutrophic Reservoir.

The high productivity of biomass registered in eutrophic water bodies, leads to qualitative and quantitative changes in the phytoplankton community, resulting in massive algae blooms. This research evaluates different atmospheric correction methods, Sen2cor and Acolite, over Sentinel-2 (S2) images and its effects for monitoring algae blooms in an eutrophic reservoir. Specifically, we analyze two dates comparing the corrected reflectance to field reflectance data and laboratory results to study the turbid and productive water of San Roque reservoir, Argentina.
