Aerosols are small liquid or solid particles in the atmosphere, like soil dust, sulphate and nitrate droplets, organic compounds, volcanic ash, etc.. Aerosols affect weather and climate by reflection and absorption of sunlight, by affecting cloud formation and precipitation, and by reducing visibility. Satellite detection of aerosols is often difficult because of the relatively weak reflectance of aerosols as compared to clouds and the background reflection of the underlying surface. Using UV-Visible spectrometers like OMI and GOME-2, UV absorbing aerosols like biomass burning smoke, volcanic ash and desert dust can be detected, even in cloudy cases and over land surfaces. In this presentation the current and future aerosol products from GOME-2 available from the O3MSAF will be introduced.
