343 Measurement and Modeling of near-Surface Soil Water and Energy Fluxes: II

Poster Session

Accurate assessment of near-surface soil water and energy fluxes is fundamental in coupling terrestrial and atmospheric hydrological processes. The magnitude and seasonality of these fluxes has a strong impact on vegetation productivity and how water partitions itself throughout all phases of the hydrologic cycle. Despite the importance of near-surface water and energy fluxes, accurate measurements are difficult and typically rely on indirect assessments. In addition, measurement of these fluxes at relevant spatiotemporal scales remains problematic, especially for calibration and verification of remotely sensed land surface properties that may be complicated by the heterogeneous distribution of vegetation and water inputs.
