Abstract :
A combined airborne and spaceborne radar remote sensing campaign on boreal forest was conducted in Tuusula, near Helsinki, in June and September 1997 in the framework of the EU EUFORA project. Airborne radar data was collected by the HUTSCAT ranging scatterometer on 6 and 12 June, and by the CARABAS SAR on 30 September. Spaceborne radar data include ERS-2 SAR images acquired on 1, 12, and 17 June. Ground truth data includes detailed information on weather, canopy, and soil parameters. The feasibility of various radar frequencies and polarizations for retrieval of forest parameters was investigated
