GlobAEROSOL (ESA Data User Element project) will produce global aerosol maps for 1995-2005 from ATSR-2, AATSR, MERIS and MSG SEVIRI data. Products will include aerosol optical depth at 550 and 865 nm, the Angstrom coefficient and level of aerosol speciation.
We present a description of the GlobAEROSOL project focus on ATSR-2, AATSR and SEVIRI aerosol products which are derived using the Oxford-RAL Aerosol and Clouds retrieval algorithm (ORAC). This optimal estimation based retrieval scheme will be described and preliminary results will be presented, including a detailed validation by comparison to ground based and other satellite data. The complete GlobAEROSOL data set is expected to be produced for use by the wider community during the coming year.
