The current project intends to use the heritage of the CAWA project as well as the recent advancements realized within the GRASP-Open software package to establish and extend the concept for generating synergy MERIS+AATSR products.
Thus, the scope of this project is to fully develop a synergy MERIS+AATSR retrieval scheme, to test it, and to eventually apply it to the full archive of MERIS and AATSR data. This GRASP/MERIS+AATSR data set is then to be validated against AERONET as reference and intercompared with other satellite-derived data sets, including existing MERIS+AATSR synergy data where available.
In addition, an optional activity of this project is to update the MERIS/GRASP and to extend the AATSR/GRASP retrieval schemes and to process the full archives of MERIS and AATSR individually to generate an updated MERIS/GRASP dataset and a new AATSR/GRASP data set. These data sets are expected to be analyzed individually and compared to the synergy MERIS+AATSR data with the purpose of improving the understanding of the information content of each instrument and the value added of MERIS+AATSR synergy processing. These individual products will serve the community when they want to use a single-instrument data set, e.g. for intercomparison exercises.
