SMAP SM and VOD retrievals (2016-2020)

The accuracy of global soil moisture (SM) and vegetation optical depth products at L-band (L-VOD) derived from the inversion of radiative transfer-based models is highly dependent on the input of soil temperature. The latter can be obtained from model-based temperature products. However, their performance as input for retrieval algorithms for global-scale SM and L-VOD has not been evaluated so far. To fill this gap, our research aims to evaluate four commonly used model-based soil temperature products as input to the SMAP-INRAE-BORDEAUX (SMAP-IB) algorithm for retrieving SM and L-VOD. More specifically, differences in SMAP-IB retrieval of SM and L-VOD were investigated based on four model-based soil temperature sources as input and four temperature configurations, including different <i>T</i>_<em>C</em> settings and <i>T</i>_<em>G</em> settings. We provide 16 group of SM and L-VOD products, and the code of TCA method.
