Improving the Capacity of U.S. Climate Modeling for Decisionmakers and End-Users

May 8, 2008

Climate models allow scientists to understand the dynamics of the climate system and predict the effects of climate change by simulating the interactions of the earth's oceans, atmosphere, land, and ice. These models assist decisionmakers in developing strategies for adapting to the impacts of climate change.

This hearing will examine the current computing capacity to process models at the regional and local scales, the need for continuous observational data to support the models, and the basic science to support the improvement of the next generation of climate models to meet the needs of decisionmakers. The hearing will focus on developing applications, consumer expectations, and network operation.
