The spectral surface albedo has been derived from MERIS on a global scale for 2002 until 2006. Means of 16 days time periods have been estimated at a spatial resolution of 0.05° pixel size. The processing of the data is based on a set of improved algorithms to account for cloud and snow detection and for atmospheric and BRDF correction.
Spectral surface albedo for different targets will be presented as well as the comparison with the MODIS albedo products.
The impact of the use of the MERIS albedo product on the retrieval of atmospheric products will be demonstrated and discussed. It will be used to improve the retrieval of cloud properties, water vapor and aerosol properties from ENVISAT-MERIS measurements. Furthermore the use in weather prediction and climate models is under investigation.
