Office of Science U.S. Department of Energy Climate Change Research Program Organized into four major groups –Climate Change Forcing Wanda Ferrell, Kiran Alapaty, Rickey Petty & Ashley Williamson and Roger Dahlman –Climate Change Modeling Anjuli Bamzai –Climate Change Response Jeff Amthor, Bob Vallario –Climate Change Mitigation Roger Dahlman

Office of Science U.S. Department of Energy Forcing: ARM - Infrastructure Continuous field measurements and data products that promote the improvement of cloud science in climate models Currently supports three fixed facilities One mobile facility –Deployed yesterday

Office of Science U.S. Department of Energy Forcing – ARM Infrastructure Successfully completed the Indirect and Semi-Direct Aerosol Campaign (ISDAC) to study properties of arctic aerosols during April and compare with those measured during the Mixed-Phase Arctic Cloud Experiment in October 2004

Office of Science U.S. Department of Energy Forcing – ARM Science Program Indirect Effect of Arctic Aerosols in the Infrared Barrow, Alaska – NSA Site – 6 years of CN measurements Increased Anthropogenic Aerosols during Arctic spring in Low level stratiform clouds leads to about 4 W/m2 increase in down-welling longwave radiation  Warmer Arctic (surface & lower atmosphere) ARM PIs: Lubin & Vogelmann, Nature, January 2006

Office of Science U.S. Department of Energy Double ITCZ Problem alleviated – JJA Precipitation Forcing – ARM Science Program mm/day New Convection Scheme Existing Convection Scheme Obs. Analysis The Community Climate System Model (CCSM) predicted double rainfall bands due to spurious second ITCZ The ARM cloud parameterization was improved to avoid this spurious additional precipitation band across the pacific ocean
