Cosmic-Ray neutron sensors are widely used to determine soil moisture on the hectare scale. Precise measurements, especially in case of mobile application, demand for detectors with high counting rates and signal-to-noise ratios. For a long time Cosmic Ray Neutron Sensing (CRNS) instruments have relied $^3$He as an efficient converter. Its ongoing scarcity demands technological solutions using alternative converters, which $^6$Li $^{10}$B. Recent developments lead modular detector consisting...
Abstract. Monitoring soil moisture is still a challenge: it varies strongly in space and time at various scales while conventional sensors typically suffer from small spatial support. With sensor footprint up to several hectares, cosmic-ray neutron sensing (CRNS) modern technology address that challenge. So far, the CRNS method has been applied with single or sparse national-scale networks. This study presents, for first time, dense network of 24 stations covered, May July 2019, an area just...
Abstract. Cosmic-ray neutron sensing (CRNS) is a non-invasive tool for measuring hydrogen pools such as soil moisture, snow or vegetation. The intrinsic integration over radial hectare-scale footprint clear advantage averaging out small-scale heterogeneity, but on the other hand data may become hard to interpret in complex terrain with patchy land use. This study presents directional shielding approach prevent neutrons from certain angles being counted while counting entering detector and...
Abstract. Cosmic-ray neutron sensing (CRNS) allows for the estimation of root-zone soil water content (SWC) at scale several hectares. In this paper, we present data recorded by a dense CRNS network operated from 2019 to 2022 an agricultural research site in Marquardt, Germany – first multi-year cluster. Consisting, its core, eight permanently installed sensors, cluster was supplemented wealth complementary measurements: seven additional temporary partly co-located with permanent ones; 27...

In this study, the performance of a new optimized scintillator-based cosmic-ray neutron detector called CRNSFINAPP for large-scale soil moisture estimation is presented and discussed. The assessment based on comparison to two commercial detectors commonly used application at experimental sites independent gravimetric measurements collected one additional irrigated cropped field. results showed good all sites, with values well in agreement different benchmarks. Thus, demonstrates be valid...

Abstract. Monitoring soil moisture is still a challenge: it varies strongly in space and time at various scales while well established sensors typically suffer from small spatial support. With sensor footprint up to several hectares, Cosmic-Ray Neutron Sensing (CRNS) an emerging technology address that challenge. So far, the CRNS method has been applied with single or sparse national scale networks. This study presents, for first time, dense network of 24 stations covered, May July 2019,...
