Abstract
    Performing a classical atmospheric correction over water requires a well defined climatology representative of the aerosols encountered in the remote areas of oceans. Different climatologies built at the global scale are candidate to be implemented as an auxiliary data file (ADF) including look-up tables (LUTs) of radiative properties of the aerosols. In addition to them, two regional climatologies have been also developed in the 2Seas region comprising both the Eastern English Channel and the North Sea, and at the Acqua Alta Oceanographic Tower (AAOT) in the Adriatic Sea. By using the optical data processor of ESA (ODESA), the MEdium Resolution Imaging Spectrometer (MERIS) level-1 data extracted from the MERis MAtchup In-situ Database (MERMAID) have been processed to get the level-2 product. For a given climatology, a processing chain has been fully developed, to generate the MERIS aerosol LUTs compatible with ODESA. The final step consisted in an analysis of the level-2 products, both for the aerosols and the water reflectance in the frame of the evaluation of the performance of each climatology in the atmospheric correction over oceans.
