Observational diagnostics of soil moisture-climate interactions as constraints to IPCC climate projections
In the present study, we investigate diagnostics that can be derived both from observations and model data in order to evaluate the accuracy of soil moisture-climate interactions in current models. The derived diagnostics are applied to IPCC AR4 simulations and used to constrain the related climate-change projections with regard to changes in climate mean and variability. Possible impacts for biogeochemical exchanges and land carbon uptake are also addressed.
