Description: Das Projekt "Remote sensing of aerosols, clouds and trace gases using synergy of AATSR, MERIS, and SCIAMACHY onboard ENVISAT" wird vom Umweltbundesamt gefördert und von Universität Bremen, Institut für Umweltphysik durchgeführt. Accurate satellite retrieval algorithms are needed to study long-term trends in trace gas abundances related to climate change. The main aim of this project is to develop improved aerosol and cloud retrieval algorithms in order to get more accurate SCIAMACHY trace gas retrievals. The results will contribute to a better understanding of aerosol and cloud properties and their changes on a global scale. This will be achieved by utilising the synergetic data from the optical instruments onboard ENVIronmental SATellite (ENVISAT), launched by the European Space Agency (ESA) on March 1st, 2002. The data of Advanced Along-Track Scanning Radiometer (AATSR), Medium Resolution Imaging Spectrometer (MERIS), and SCIAMACHY, all of which measure the same ground scene, will be used. The three instruments continue to have excellent performance and have already generated more than five years of data. Compared to just one single instrument, combined data from these optical instruments having different spatial resolutions, observation modes, spectral resolutions and spectral bands characterize aerosol, cloud, and trace gas properties to a much better degree. In this project, a new validation and testing strategy based on extended realistic simulated satellite scenes will be followed.
