The UK Centre for Ecology & Hydrology has established, and continues to grow, a long-term network of soil moisture monitoring sites for the United Kingdom, with funding from the Natural Environment Research Council. The network provides near-real time soil moisture data for use in a variety of applications including farming, water resources, flood forecasting and land-surface modelling. Each site is equipped with an instrument that uses cosmic-rays to sense soil moisture over an area of about 12 hectares (about 30 acres). Data from the network have the potential to transform the way that we understand and model the natural environment.
