DOE/UCAR Cooperative Agreement for the Regional and Global Climate Modeling Program

The U.S. Departmentof Energy (DOE) has supported climate change research at the national Center for Atmospheric Research (NCAR) since 1978.  A DOE/UCAR Cooperative Agreement for the Regional and Global Climate Modeling Program has been in place since 1997 with DOE's Office of Science and the University Corporation for Atmospheric Research (UCAR) to model future climate change and conduct extensive analyses into how the climate system responds to various climate forcings.  This research also evaluates and improves components of climate and Earth system models, performs process studies using model versions of varying complexity and resolution, and applies climate dynamics to climage change. 

One unique contribution is its role within the Climate and Variability and Change Working Group in connection to the Community Climate System Model/Community Earth System Model (CESM).  On average, this project produces 30 peer-reviewed papers each year.  To ensure Cooperative Agreement science is integrated into national and international research agendas, scientists play leadership roles in the CESM, World Climate Research Programme, National Research Council, and in climate assessments.  Climate change simulations performed as part of the Cooperative Agreement have made major contributions to the Intergovernmental Panel on Climate Change reports.
