Description
Hydrological monitoring using cosmic ray neutrons is strongly dependent on heliospheric and geomagnetic conditions. To correct for changes in the heliosphere, the most common approach is to use neutron monitor data. Multiple neutron monitor-based correction methods have been proposed. The derivation, inherent assumptions, and limitations of these methods were examined and a novel method derived. Further, a model-based approach is also introduced.
All correction methods were evaluated on long-term neutron monitor data and their impact assessed using artificial cosmic ray neutron sensor data.
