2. Acknowledgements

The authors wish to acknowledge members of NCAR’s Atmospheric Modeling and Predictability Section (AMP), Computer Software and Engineering Group (CSEG), and Computation and Information Systems Laboratory (CISL) for their contributions to the development of CAM5.0.

The new model would not exist without the significant input from members of the CESM Atmospheric Model Working Group (AMWG) too numerous to mention. Leo Donner (GFDL), Minghua Zhang (SUNY) and Phil Rasch (PNNL) were the co-chairs of the AMWG during the development of CAM5.0.

We would like to acknowledge the substantial contributions to the CAM5.0 effort from the National Science Foundation, Department of Energy, the National Oceanic and Atmospheric Administration, and the National Aeronautics and Space Administration.
