| Zusammenfassung |
| Soil moisture is an essential climate variable (ECV) of major importance for
land–atmosphere interactions and global hydrology. An appropriate
representation of soil moisture dynamics in global climate models is
therefore important. Recently, a first multidecadal, observation-based soil
moisture dataset has become available that provides information on soil
moisture dynamics from satellite observations (ECVSM, essential climate
variable soil moisture). The present study investigates the potential and
limitations of this new dataset for several applications in climate model
evaluation. We compare soil moisture data from satellite observations,
reanalysis and simulations from a state-of-the-art land surface model and
analyze relationships between soil moisture and precipitation anomalies in
the different dataset. Other potential applications like model parameter
optimization or model initialization are not investigated in the present
study. In a detailed regional study, we show that ECVSM is capable to capture
well the interannual and intraannual soil moisture and precipitation dynamics in
the Sahelian region. Current deficits of the new dataset are critically
discussed and summarized at the end of the paper to provide guidance for an
appropriate usage of the ECVSM dataset for climate studies. |
