Focus Topic: Remote Sensing of the Vadose Zone

Remote sensing techniques have become more and more important in characterizing vadose zone properties and processes and to inform vadose zone models. This focus topic collects research in the field of remote sensing and presents original fundamental or applied papers on the impact of soil on energy, water, and nutrient fluxes; catchment scale processes; vegetation cover and terrain dynamics; and calibration and validation of various remote sensing techniques for hydrological simulations at the plant, soil, and atmosphere continuum.

The COsmic-ray Soil Moisture Observing System (COSMOS) rover was used to map soil moisture for two regions in Oklahoma: a 16- by 10-km and a 34- by 14-km region. The 0- to 5-cm soil moisture determine...more
