Project Summary

Accurate information on the atmospheric evaporative demand (i.e., thirst of the atmosphere) and the land-surface evaporative response (i.e., moisture supply on the land to meet the evaporative demand) is extremely important to assessing water stress on the land surface. In this webinar, the presenters will introduce real-time high resolution (1-10km) monitoring products of atmospheric evaporative demand and land-surface evaporative response models that are currently available to users. They will also discuss the physical relationships between these systems, as well as the potential of the monitoring products discussed above to markedly improve scientists and managers understanding of drought processes (i.e., onset, evolution, persistence and dissipation), and develop a more robust drought early warning framework.
