GRASP

GRASP (Generalized Retrieval of Aerosol and Surface Properties) retrieves both properties of aerosol and surface reflectance from PARASOL/POLDER observations. GRASP performs atmospheric radiation calculation on line. The retrieval is implemented as statistically optimized fitting and retrieves extended set of aerosol parameters including size distribution, complex refractive index, and fraction of non-spherical fraction. GRASP uses multi-pixel retrieval approach when retrieval is performed simultaneously for a group of observed satellite pixels. This principle allows for improving robustness of the retrieval by using additional constraint on temporal and spatial variability of retrieved parameters.
