C-band radiometric response to rainfall events in the subtropical Chaco Forest

In this letter, multitemporal signatures collected by Advanced Microwave Scanning Radiometer (AMSR-E) over the dry forest of Chaco, located in North Argentina, are analyzed. The forest has a biomass of about 100 t/ha and a woody volume of about 120 m 3. A clear increase of polarization index at C-ba...
