European daily dataset of soil moisture from in situ meteorological observations
This dataset contains a pan-European dataset with time series for soil water content. For a total of 5758 stations (status January 2026) daily soil water content values are produced for the period for which all input data is available. Input data is from the European Climate Assessment & Dataset (ECA&D, https://www.ecad.eu) and are daily precipitation totals, daily averaged temperature, and global radiation sums. These data are input to the SoilClim model (Hlavinka et al. 2011, doi:10.1016/j.agwat.2011.03.011) which provides soil water contents values for the upper 10 cm, the root zone and the deeper layer of the soil. In this dataset, values for the surface and root zone are provided. Soil characteristics are taken from the widely used SoilGrids system (Hengl et al. 2017, doi:10.1371/journal.pone.0169748).

The purpose of the dataset is principally to monitor drought conditions in Europe and to provide a historic perspective of recent droughts in terms of its most direct metric: soil moisture. In addition, the dataset serves as a validation dataset to the climate modelling and satellite communities for their soil moisture datasets.

The SoilClim model results are validated against observations of actual evapotranspiration (ETa) from the FluxNet experiment. Calculated soil water content are compared against a selection of the observations of the International Soil Moisture Network (ISMN). In the comparisons against observations, calculated values of ETa and soil water content (SWC) from the state-of-the-art soil dynamics model SWAP, which is more advanced than SoilClim, are used as well. The comparisons show that SoilClim and SWAP show generally the same behaviour albeit that SoilClim saturates more quickly than SWAP. On average, the similarity between the models and observation for ETa is higher (correlations 0.77 and 0.78 for SWAP and SoilClim respectively) than for the observed soil water content, where average correlations for the surface and rootzone vary between 0.52 and 0.62.
