A SURFACE ALBEDO PRODUCT AT HIGH SPATIAL RESOLUTION FROM A COMBINATION OF SENTINEL-2 AND LANDSAT-8 DATA: THE ROLE OF SURFACE RADIATIVE FORCING FROM AGRICULTURE AREAS AS A MAJOR CONTRIBUTOR TO AN ABATEMENT OF CARBON EMISSION

摘要

Satellite Sentinel-2 offers a global coverage of the Earth surface at the frequency of a few days with pixel size ranging from 10 to 60 meters. Such spatio-temporal resolution fosters an advanced research in agricultural area notably. The role of the surface albedo as a mean to reduce the surface radiative forcing in link to agriculture practice is a real concern. A high resolution (HR) surface albedo is now generated routinely from the observations of satellites Sentinel-2A & -2B for the time being plus Landsat in the near future. The methodology inherited from the Global Land Service of Copernicus is presented with some preliminary results.
