N2 - An X-band FM-CW very fine range resolution scatterometer was used to acquire backscattering data for individual branches for a number of tree species. Using a model to describe the scattering source function, [formula omitted], and an experimental procedure for selected removal of plant parts, allows the estimation of [formula omitted], the volume backscatter coefficient, and [formula omitted], the volume extinction coefficient. It is found that 1) leaves are strong attenuators as well as scatterers, 2) the albedo, [formula omitted], at a given angle of incidence, is nearly independent of the tree type, 3) the tree limbs are good attenuators but rather poor scatterers, and 4) the albedo changes as a function of the angle of incidence and for deciduous trees is also a function of the season.
