EXPLORING DESIS FOR INLAND WATER QUALITY IN SPANISH RESERVOIRS

Abstract. In a first approximation to the use of hyperspectral DESIS data to ocean colour applications in inland waters, we present here a comparison of the DESIS vs. MSI spectra from two reservoirs located in the province of Valencia. Benagerber and Tous are two small, oligo-mesotrophic reservoirs in need of constant water quality monitoring. These preliminary results have shown us the advantages and limitations of DESIS imagery for these types of dark and small lakes, but also pointed out the need for a specific over water atmospheric correction, as well as further understanding of the band combinations that can lead to accurate water quality parameter estimations.
