The main objective of this task is to develop new methods for determining the spatial distribution of woody biomass and carbon stock based on radar data acquired from the newest radar satellites like ALOS 2 (band L), Sentinel-1 (band C) and TerraSAR-X (band X). This will be achieved by new method of radar data processing elaboration using polarimetric and interferometric techniques to create products better correlated with real biomass than previously used.
