Acknowledgments

The authors wish to acknowledge other members of the Climate Modeling Section, Julie Caron, Brian Eaton, Erik Kluzek, Jerry Olson, Jim Rosinski, John Truesdale, and Mariana Vertenstein for all their contributions to the development of the CAM2. The new model would not exist without the significant input from members of the CCSM Atmospheric Model Working Group (AMWG, http://www.cesm.ucar.edu/working_groups) too numerous to mention. David Randall (CSU) and James Hack (NCAR) were the co-chairs of the AMWG during the development of CAM2. Mark Stevens helped accelerate the creation and testing of the new model with his advanced diagnostics package. Tony Craig helped oversee the integration of CAM2 into the NCAR CCSM.

We also wish to thank Mark Stevens and Paula Drager for their invaluable help in the preparation of this document. Finally, we would like to thank four anonymous reviewers for their close reading and thorough critique of this document.
