Short summary
Cosmic-ray neutron sensors bridge the gap between point-scale measurements of soil moisture and remote sensing applications. We tested four distinct methods to calibrate the sensor in a temperate forest environment using different soil moisture weighting approaches. While the variable leaf biomass of the deciduous trees had no significant influence on the calibration, it proved necessary to modify the standard calibration method to achieve the best sensor performance.
