ASSESSMENT OF PRISMA ATMOSPHERIC CORRECTION IN HYPERTROPHIC INLAND WATERS USING 6S AND IN SITU SPECTROSCOPY DATA

The atmospheric correction of hyperspectral remotely sensed images for the retrieval of biogeochemical variables in
hypertrophic inland waters is an area of ongoing research. We implemented a radiative transfer model (RTM) processing
scheme based on 6S (Second Simulation of the Satellite Signal in the Solar Spectrum) to extrapolate from PRISMA L1 topof-atmosphere radiance data to above-water remote sensing reflectance (Rrs) in a hypertrophic water reservoir located in Valencia, Spain. We obtained a very good agreement
between the in–situ and the atmospherically corrected Rrs (R2 = 0.89, RMSE = 0.0017 sr−1) within the 400–900 nm wavelength range.
