Technical note: A revised incoming neutron intensity correction factor for soil moisture monitoring using cosmic-ray neutron sensors

Magdalena Szczykulska, David Boorman, James Blake, and Jonathan G. Evans

Abstract. The cosmic-ray neutron sensor method of soil moisture measurement is now widely used and is fundamental to the COSMOS-UK soil moisture monitoring network. The method is based on a relationship between a measured flux of neutrons and soil moisture, and requires the neutron count to be adjusted for time variations of atmospheric pressure, humidity and the incoming flux of cosmic-ray neutrons. This note describes an empirical approach to the development of a revised correction factor for the last of these. Using the revised correction factor makes a significant difference to the derived soil moisture at wetter sites. This has implications for quantifying the soil moisture regime at these sites and management decisions that depend on a proper understanding of soil moisture dynamics, such as flood management and the release of greenhouse gases.

Short summary
In this note, a revised incoming neutron intensity correction factor for soil moisture monitoring using cosmic-ray neutron sensors (CRNSs) is presented. The correction takes into account the incoming neutron flux differences at the reference neutron monitoring and soil moisture sites. When applied to the COSMOS-UK soil moisture data, it reduces the otherwise unexplained trend present in the data at wetter sites. It has implications for better soil moisture quantification using the CRNS method.
