 The soil moisture and ocean salinity, SMOS, mission is designed to provide global maps of soil moisture and vegetation optical depth using brightness temperatures measured at L-Band. However, the operational SMOS level 3, SMOSL 3, product requires auxiliary data to account for surface effects like vegetation opacity and soil roughness, resulting in a more complicated algorithm. To simplify the process, researchers have developed the SMOS INRASESBIO, SMOSIC, product which uses a single-angle approach to retrieve soil moisture and optical depth without requiring auxiliary data. This new product has been shown to outperform the operational SMOSL 3 product in terms of correlation and accuracy.
