Global joint assimilation of GRACE and SMOS for improved estimation of root-zone soil moisture and vegetation response

Tian, Siyuan; Renzullo, Luigi; Van Dijk, Albert; Tregoning, Paul; Walker, Jeffrey


The lack of direct measurement of root-zone soil moisture poses a challenge to the large-scale prediction of ecosystem response to variation in soil water. Microwave remote sensing capability is limited to measuring moisture content in the uppermost few centimetres of soil. The GRACE (Gravity Recovery and Climate Experiment) mission detected the variability in storage within the total water column. However, root-zone soil moisture cannot be separated from GRACE-observed total water storage...[Show more]
