SMAPVEX12 is a pre-launch field campaign for evaluating and testing the soil moisture retrievals retrieved from the
SMAP project. During this experiment, airborne microwave observations from PALS radiometer and radar: brightness
temperature and radar backscatter, as well as ground measurements were acquired. In this study, the remote sensing soil
moisture was retrieved from SMAPVEX12 PALS radiometer L-band (6GHz) brightness temperature at high altitude
flight. The PALS soil moisture was then aggregated and compared with PALS radar backscatter coefficient to generate
high spatial resolution microwave soil moisture in change. The R2 values of PALS soil moisture retrieval validation
range from 0.407-0.881, indicating good accuracy of soil moisture retrieval. The R2 values of comparison between
aggregated PALS Δ and PALS Δ range from 0.492-0.805, while the downscaled Δ validation range from 0.128-
0.383.
