      abstract     = {Cosmic-ray neutron sensing (CRNS) has become an effective
                      method to measure soil moisture at a horizontal scale of
                      hundreds of metres and a depth of decimetres. Recent studies
                      proposed operating CRNS in a network with overlapping
                      footprints in order to cover root-zone water dynamics at the
                      small catchment scale and, at the same time, to represent
                      spatial heterogeneity. In a joint field campaign from
                      September to November 2020 (JFC-2020), five German research
                      institutions deployed 15 CRNS sensors in the 0.4 km2
                      Wüstebach catchment (Eifel mountains, Germany). The
                      catchment is dominantly forested (but includes a substantial
                      fraction of open vegetation) and features a topographically
                      distinct catchment boundary. In addition to the dense CRNS
                      coverage, the campaign featured a unique combination of
                      additional instruments and techniques: hydro-gravimetry (to
                      detect water storage dynamics also below the root zone);
                      ground-based and, for the first time, airborne CRNS roving;
                      an extensive wireless soil sensor network, supplemented by
                      manual measurements; and six weighable lysimeters. Together
                      with comprehensive data from the long-term local research
                      infrastructure, the published data set (available at
                      https://doi.org/10.23728/b2share.756ca0485800474e9dc7f5949c63b872;
                      Heistermann et al., 2022) will be a valuable asset in
                      various research contexts: to advance the retrieval of
                      landscape water storage from CRNS, wireless soil sensor
                      networks, or hydrogravimetry; to identify scale-specific
                      combinations of sensors and methods to represent soil
                      moisture variability; to improve the understanding and
                      simulation of land–atmosphere exchange as well as
                      hydrological and hydrogeological processes at the hillslope
                      and the catchment scale; and to support the retrieval of
                      soil water content from airborne and spaceborne remote
                      sensing platforms.},
