Quantification of bio-geophysical variables of different surfaces is essential for understanding the earth system and for the development of earth system models for prediction of climate and environmental change. Understanding these variables remains problematic due to a lack of observational data at appropriate scales. Therefore this research campaign was carried out. A large scale of data was measured, for example satellite, air-borne, atmospheric, ground radiometric and flux tower data was collected.
