      abstract     = {At the land surface, the hydrologic cycle is strongly
                      linked to soil water content (SWC). Land surface models
                      describe the mass and energy fluxes at the land surface and
                      to the atmosphere with a spatial resolution of a few
                      km$^{2}$ at the catchment scale. The calibration and
                      evaluation of land surface models requests observation data,
                      ideally at the same spatial resolution. SWC characterization
                      by model prediction and observation remains a challenge in
                      land surface hydrology. Recently, cosmic-ray probes (CRPs)
                      were developed for continuous passive SWCe stimation from
                      neutron flux measurements at a scale relevant for land
                      surface models. One objective of this work was to set up a
                      network of ten CRPs and to evaluate SWC estimates by CRPs.
                      For evaluation, the footprint average SWC of the CRPs was
                      compared to the horizontally and vertically weighted signal
                      of two distributed networks of in-situ SWC sensors. Three
                      different parameterization methods to estimate SWC from
                      neutron flux were compared. Numerical complexity and
                      potential applications distinguish the three
                      parameterization methods. The three parameterization methods
                      resulted in close SWC estimates at the ten study sites
                      although the neutron flux – SWC relationships were
                      slightly different amongst the parameterization methods. SWC
                      estimated by the calibrated CRPs was very close to SWC
                      measured by alternative SWC measurements. Root mean square
                      errors (RMSEs) of the SWC were 0.031 cm$^{3}$/cm$^{3}$ at
                      the distributed in-situ SWC sensor networks. [...]},
