GRASP Earth - Version GROSAT -Generalized Retrieval of Aerosol and Surface Properties (GRASP) Software

In the framework of ESA “Synergetic retrieval from Ground-based and Satellites measurements: new possibilities for surface characterization and validation” (GROSAT) project, a simultaneous synergistic retrieval of aerosol and surface properties approach (GRASP/GROSAT approach) is developed using combined ground-based AERONET and satellite measurements. In such retrieval the main information about aerosol comes from AERONET direct sun and diffuse sky-radiance measurements, whereas the information about surface reflection properties originates from satellite observations. Such approach allows obtaining the surface reflectance product with enhanced accuracy.
