The main scientific objectives of the VAS are:
- Definition of a large scale validation area for low-spatial resolution missions.
- Definition and characterisation of a large scale reference pixel.
- Study of scaling issues. Time Interpolation and Spatial Averaging.
VAS takes part in validation and calibration activities of satellite sensors corresponding to several missions such as EarthCARE (Earth Clouds, Aerosols and Radiation Explorer) and CERES (Clouds and the Earth’s Radiant Energy System).
