Effect of Structural Uncertainty in Passive Microwave Soil Moisture Retrieval Algorithm
Passive microwave sensors use a radiative transfer model (RTM) to retrieve soil moisture (SM) using brightness temperatures (<i>T<sub>B</sub></i>) at low microwave frequencies. Vegetation optical depth (VOD) is a key input to the RTM. Retrieval algorithms can analytically inv...
