A novel Soil Moisture Retrieval Method Using the First Stokes Parameter: A Case Study with SMOS data

Soil moisture is a crucial variable in the climate system. This letter undertakes the retrieval of soil moisture using data from SMOS, which is equipped with an L-band microwave synthetic aperture radiometer. The multi-angle brightness temperature (TB) of the synthetic aperture radiometer is affected, to varying degrees, by factors such as the aliasing effects, ionospheric disturbance, and radio frequency interference. This, in turn, impacts the subsequent inversion of land surface parameters li
