Soil moisture is measured continuously with the wireless sensor network SoilNet (Bogena et al., 2010). The sensor network in the Wuestebach test site was installed in 2008 and consists of 150 end device units. Soil moisture data are interpolated into a 5x5 m grid for each depth by Ordinary Kriging using the daily mean of the maximum value of the two sensors measurements at each depth. Obviously wrong data or data, which have been assigned as being incorrect are not used. Semivariograms are estimated for each time step and depth using a spherical model. Validity of the Kriging estimation is checked by cross validation. For each time step a reporting document is created and stored to allow for further analyses
GPR data was acquired in crosshole setup before (background) and after (time-lapse) hot water tracer injection for 4 planes. In total 39 datasets were measured.
GPR data was acquired in crosshole setup before (background) and after (time-lapse) salt tracer injection. Plane 2926 includes 2 datasets: the background and day 1 following the injection.
