We evaluated SMOS L2 and L3 soil moisture products in central Tibetan Plateau. Evaluation shows the accuracy of SMOS product is scale-dependent. Large biases exist at SMOS node scale while reduced at 100-km scale. We then assimilated the 100-km averaged SMOS L2 data into a land surface model, and robust surface soil moisture estimate is achieved.
