Creating Foundational Knowledge in Hydrometeorological Process Understanding Through Strategic Observational Capabilities

Observations of hydrometeorological processes provide foundational understanding of how weather and hydrologic phenomena combine to create both societal risks and key societal resources.  The Hydrometeorological Applications Program has developed and deployed innovative observations in field programs around the world to create new knowledge.  Several of these projects are described in the links to the right of this page and they detail ongoing work in a variety of climate and physiographic settings.  These new observations also become the cornerstone of building robust hydrometeorological predictive models which, in turn, help us prepare for extreme events and environmental change.
