Abstract :
The skill of root zone soil moisture estimates derived from assimilating satellite retrievals of surface soil moisture into a land surface model depends, among other factors, on the specific structure of the land model. Based on a suite of synthetic data assimilation experiments with four different land surface models we find that it is prudent to use a simpler land surface model as part of the data assimilation system.
