Translating aboveground cosmic-ray neutron intensity to high-frequency soil moisture profiles at sub-kilometer scale

Above-ground cosmic-ray neutron measurements provide an opportunity to infer soil moisture at the subkilometer scale. Initial efforts to assimilate those measurements have shown promise. This study expands such analysis by investigating (1) how the information from aboveground cosmic-ray neutrons can constrain the soil moisture at distinct depths simulated by a land surface model, and (2) how c...

Adsorption of arsenic on soil under different soil moisture conditions

The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...

Soil Moisture and Biogeochemical Factors Infl uence the Distribution of Annual Bromus Species

Abiotic factors have a strong infl uence on where annual Bromus species are found. At the large regional scale, temperature and precipitation extremes determine the boundaries of Bromus occurrence. At the more local scale, soil characteristics and climate infl uence distribution, cover, and performance. In hot, dry, summerrainfall-dominated deserts (Sonoran, Chihuahuan), little or no Bromus is ...

Dual-low-frequency Radar for Soil Moisture under Vegetation Andat-depth

To address a key science research topic for the global water and energy cycle, namely measuring soil moisture under substantial vegetation canopies and to useful depths, we have developed a concept for a synthetic aperture radar (SAR) system operating simultaneously at UHF and VHF frequencies. We are currently prototyping key technology items that enable this concept under the NASA Earth Scienc...
