Dataset of "COSMOS-Europe: A European network of Cosmic-Ray Neutron Soil Moisture Sensors"

Here we provide the dataset for COSMOS-Europe: A European network of Cosmic-Ray Neutron Soil Moisture Sensors. The dataset contains soil moisture data from 65 cosmic-ray neutron sensors (CRNS) in Europe. The CRNS stations cover all major land use types and climate zones within Europe. Raw neutron count data from the CRNS stations were provided by 23 research institutions and processed using state-of-the-art methods. The harmonized processing included correction of the raw neutron counts and a harmonized methodology for conversion to soil moisture based on available in situ information. In addition, information on data uncertainty was added to the dataset, which is particularly useful for remote sensing and modeling applications. This harmonized European soil moisture dataset will help both the hydrological and climatic communities to study individual drought events, understand their causes, evaluate and improve their modeling, and estimate the extremity of current events.
