Abstract
Soil moisture plays the critical role in land-surface processes. But it is not well understood,in part because of its strong spatial variability that makes difficult obtaining representativemeasurements. The recently developed cosmic-ray soil moisture probe provides the means forsuch representative measurements and therefore has the potential to provide usefularea-average data for land-surface hydrology.

Key words: cosmic-ray neutrons, soil moisture, land surface hydrology, measurement method

Soil moisture is the most important part of the water and energy cycle (Fig. 1). It plays acritical role in weather and seasonal climate forecasting, and in linking water, energy, andbiogeochemical cycles over land. But our understanding of water at the land surface is poor, inpart because of the mismatch between the scales at which processes above and below the land
surface are observed, parameterized and modeled. In the well-mixed atmospheric boundary
layer that scale is from hectometers to tens of kilometers. Below the surface, states and fluxes
are usually measured at a point. To remove the mismatch, the subsurface must be
characterized at the scale comparable to that above the land surface. I call it the useful scaleand define it as a range 100 m – 1000 m that broadly matches the needs of futurehigh-resolution land-surface and hydrological models.
Area-average water states and fluxes are difficult to measure at the useful scale. Point
measurements are not representative because of strong spatial heterogeneity (e.g., Zreda etal., 2012), and must be upscaled, which is impractical. Scale-integrating methods for soil
moisture, such as satellite microwave methods, measure over large areas (10 km – 50 km),integrate meteorological, topographic and other factors, and must be downscaled, which isuncertain.
The cosmic-ray method (Fig. 1) (Zreda et al., 2008, 2012; Desilets et al., 2010), with thehectometer footprint, integrates out small-scale variations, but is not affected by large-scalevariability. It is, therefore a good scale integrator. In this review, I discuss the principles of thecosmic-ray method, the instruments for measuring cosmic-ray neutrons, the methodology forconverting neutron data to moisture, and some applications to land-surface hydrology.
