A universal calibration function for determination of soil moisture with cosmic-ray neutrons (2012, background): “The support volume of a cosmic-ray probe is governed by the average travel distance of neutrons in air near the land surface (Desilets et al., 2010). Because of the additional sources of hydrogen, it is difficult to isolate a single transient signal (here, soil moisture) from the convoluted detected”
The Effect of Atmospheric Water Vapor on Neutron Count in the Cosmic-Ray Soil Moisture Observing System (2013, methodology): “…to all forms of moisture present near the surface, including water present in the crystal lattice of minerals and ponded water (Franz et al. 2012a), snow (Desilets et al. 2010), organic matter (Franz et al. 2012a), vegetation (Hornbuckle et al. 2012; Franz et al. 2013b), and the atmosphere.”
Measurement depth of the cosmic ray soil moisture probe affected by hydrogen from various sources (2012, methodology): “More recently, fast neutron intensity has been shown to be sensitive to hydrogen present in liquid and frozen water on the ground surface and on the vegetation canopy [Desilets et al., 2010].”
Footprint characteristics revised for field‐scale soil moisture monitoring with cosmic‐ray neutrons (2015, background): “Moreover, Franz et al. [2013b] show that large heterogeneous structures in the footprint can affect the average soil moisture signal apparent to sensors, because the neutron density and water content are nonlinearly related [Desilets et al., 2010].”
Footprint diameter for a cosmic‐ray soil moisture probe: Theory and Monte Carlo simulations (2013, methodology): “In our simulations, we specify that in order to be detected the neutron must also be within 2 m of the land surface, which is where our detectors are typically installed for static operations [e.g., Zreda et al., 2008; Desilets et al., 2010; Zreda et al., 2012].”
