This study is based on model integrations that were performed by NCAR and CRIEPI with support and facilities provided by NSF, DOE, MEXT, and ESC/JAMSTEC. This work would not have been possible without the concerted effort of the entire staff of the Climate and Global Dynamics Division at NCAR who are responsible for creating and running CCSM3. We thank George Carr for the data on CCSM3 computational performance.
