reportActive / Technical Report | Accession Number: ADA452180 | Open PDF

Abstract:

This study demonstrates a technique of estimating soil moisture using the combined passiveactive L-band microwave measurements. It shows 1 evaluation of the small albedo assumption for using dual polarization passive measurements, 2 development of a synthesized technique to estimate soil moisture, and 3 evaluation with ground soil moisture measurements from the SMEX02 experiment data.
