Abstract

We have studied usage of our airborne L-band 2-D synthetic aperture radiometer HUT-2D for estimation of soil moisture. Measurements were conducted over three sites in Northern and Southern Finland in August 2007. Good results were achieved for bare soil and low vegetation, whereas soil moisture retrieval for forested areas requires further studies.
