Interpolation

Abstract

The paper evaluates 7 global root-zone soil moisture products and one regional product over the Huai river basin in China for the period from April 2015 to March 2020. The products are evaluated against each other and against in situ measurements from 58 sensor profiles. The differences in the products and their performance against in situ measurements is related to the skill of the products’ forcing inputs (precipitation, air temperature), model structure, and model parameters (soil texture).
