The objective was to acquire a data set for studying a combined radiometer-radar-radar multifrequency, multi-polarization approach to soil moisture sensing under varied terrain conditions. Six days of PALS flight data were acquired over the Little Washita and El Reno areas in Oklahoma, in conjunction with ground-based soil and vegetation in-situ sampling. The data illustrate the different sensitivities of the PALS channels to soil moisture, temperature, surface roughness, and vegetation cover. This will provide a basis for development of passive and active multi-channel algorithms for soil moisture sensing. |
