- A New GEWEX Regional Hydroclimate Project: Understanding the Water & Energy Cycles of the Continental United States in the Anthropocene
Primary Convener: Peter van Oevelen (George Mason U.)
Convener(s): Timothy Schneider (NCAR/RAL)
Recognizing the interdependence of both ecosystems and humans on the physical and biogeochemical Earth systems, a better and more thorough understanding of the key processes driving the water and energy cycles is needed. In particular, this includes the human drivers and influences on these processes. To this end, a new Global Energy and Water Exchanges (GEWEX) Regional Hydroclimate Project (RHP) is being proposed, a large-scale collaborative effort with the aim of advancing the
state-of-the-science and an objective of closing the coupled water and energy budgets for the continental United States. The envisioned RHP will employ a strategy of advanced observations, high-resolution coupled modeling, and interdisciplinary science from various institutions and agencies to meet this objective. This session seeks to inform the community about the GEWEX US RHP, and invites scientific and programmatic papers to advance and support it.
