Abstract:

The Passive Active L- and S-band sensor (PALS) is a combined polarimetric radiometer that combines a real-aperture, combined microwave radiometer and active radar, operating at 1.413 GHz and 1.26 GHz respectively. PALS was recently update to include a rotating scanner (PALScan). It is the prototype for the SMOS, Aquarius and SMAP missions and recently flow over the Texas Soil Observation Network (TxSON). Four airborne missions were conducted on April 30, May 2, May 8, and June 25, 2015. In situ data from over 40 soil moisture stations were combined to assess scaling functions to reproduce mean soil moisture equivalent to 3-, 9-, and 36-km footprint of the SMAP satellite.
