Soil moisture from invasive sampling, capacitance sensor network and cosmic-ray neutron sensing at Katharinentaler Hof (Germany), April to August 2013
Description
The data set accompanies the manuscript:
Scheiffele, L. M., Munz, M., Francke, T., Baroni, G., Oswald, S. E. (2024) "Enhancing hectare-scale groundwater recharge estimation by integrating data from cosmic-ray neutron sensing into soil hydrological modelling" (to be submitted to Water Resources Research).
This dataset provides soil moisture measurements collected at the EC1 experimental site located near Katharinentaler Hof, Kraichgau, Germany, spanning from April to August 2013. Soil moisture was continuously monitored using cosmic-ray neutron sensing (CRNS) and a network of capacitance sensors. Additionally, four invasive soil moisture sampling campaigns were conducted to complement the dataset, allowing for calibration of the CRNS.
The EC1 site is situated within a cluster of eddy covariance stations, as extensively documented in a dat apaper by Weber et al. (2021). However, the detailed soil moisture dataset presented here is not included in their data set.
Additionally, HYDRUS 1D model files as used for the soil moisture and water flux simulations to create the results of the manuscript are provided.
Other
Separate text files are provided for the capacitance sensor network, the cosmic-ray data (neutron counts), and the calibration soil sampling. Each file is accompanied by a JSON file containing metadata and additional information to aid in the utilization of the dataset. The zip-folder contains files for two consecutive HYDRUS 1D models, spanning the time frame from January to August 2013 and August 2013 to March 2014, as used to produce the results of the study. A more detailed description is contained in a JSON file in the folder. While the provided models are the uncalibrated model, a table containing all the parameter sets from different calibration is provided as well.
