GRASP Earth - Version MERIS/ENVISAT -Generalized Retrieval of Aerosol and Surface Properties (GRASP) Software

SHARE

Within the framework of projects supported by ESA, GRASP algorithm has been optimized and applied to the data of MERIS instrument. Two important results have been obtained from those studies:

  • The information about surface and aerosols (aerosol optical depth, single-scattering albedo, etc.) for the entire MERIS mission has been obtained. Full archive is available for free at this website. Click the button below to download the data.
  • A reimplementation of GRASP forward model using GPGPU technologies has been developed successfully, allowing the code to run parallelized over graphic cards and obtaining faster results (up to 100x). This developments work as external and optional module for GRASP. It is going to be released as an open source and can be selected at compilation time.
