Aerosols have a significant contribution to the Earth radiative budget. MSG offers new capabilities to monitor aerosol transport over the Atlantic and the Mediterranean at high temporal and spatial resolutions, in particular Saharan dust from North Africa, biomass- burning aerosols from subtropical Africa and pollution plumes from Europe. We developed an inversion technique using MSG bands at 0.6 and 0.8 µm to estimate both aerosol optical thickness and Angström coefficient. The code is written in Fortran 95 and optimized for a fast processing of full-resolution MSG imagery, thus allowing to process long MSG time series. This inversion technique was applied to MSG slots 45, 49 and 53 (11:15, 12:15, 13:15 UT) of June 2003. The retrieved optical thicknesses and Angström coefficients are in good agreement with AERONET in situ measurements in the Atlantic and in the Mediterranean. Monthly mean maps of both parameters also demonstrate the potential of the method.
