Lay Summary (Englisch)

Lay summary
In this project we conduct a three-year (2008-2011) soil moisture monitoring experiment in Switzerland, which allows a comprehensive assessment of soil moisture in our region. Soil moisture is a key variable of the climate system, which can impact temperature and precipitation regionally (and globally). Due to the current enhancement of temperature and soil drying associated with global warming in Central Europe, its impact on the Swiss climate is expected to become increasingly important. The relevant processes, however, are not well investigated, because detailed measurements are generally not available in most regions of the world. This is in particular the case in Central Europe and Switzerland. This project will allow for the first time to assess the spatial and temporal variability of soil moisture in Switzerland and to investigate the potential of soil moisture monitoring for the improvement of climate and meteorological modeling.

Soil moisture is a key variable of the climate system: It impacts the partitioning of the incoming radiation on land in the sensible and latent energy fluxes, with consequent effects on the near-surface climate (temperature, humidity), boundary-layer processes (e.g. convective precipitation), and potentially circulation. Moreover, as a storage element, it represents an important memory component for the regional climate system, with attendant high potential for seasonal forecasting. It is however not routinely measured in most parts of the world, particularly in Europe, where measurement datasets are scarce. In this project we propose to conduct a three-year (2008-2010) soil moisture monitoring experiment in Switzerland that will allow a comprehensive assessment of soil moisture in this region. Measurements will be conducted at 15 sites, including the Rietholzbach research catchment site ( seneviratne/research/rietholzbach), the presently operational 6 SwissFluxnet sites (, and 9 selected SwissMetNet ( stations. The focus of the measurements and their analysis will be on the following aspects: 1) the assessment of the spatial variability of soil moisture and the determination of characteristic spatial scales for intra- and inter-sites variability; 2) the assessment of the temporal variability of soil moisture and its link with the main climate drivers (radiation, precipitation); 3) the determination of the impact of soil moisture for the local and regional climate (feedbacks) and of its potential for weather and seasonal forecasting in Switzerland; 4) the investigation of regionalization approaches; 5) the evaluation of indirect measurement techniques and approaches (diagnostic estimates; satellite measurements, in particular from the SMOS mission); 6) the validation of land surface and climate models with regard to soil moisture representation in Central Europe.
