We evaluate the climate produced by the Community Earth System Model, version 1, running
with the new spectral-element atmospheric dynamical core option. The spectral-element method
is con gured to use a cubed-sphere grid, providing quasi-uniform resolution over the sphere,
increased parallel scalability and removing the need for polar fi lters. It uses a fourth order accurate
spatial discretization which locally conserves mass and moist total energy. Using the Atmosphere
Model Intercomparison Project protocol, we compare the results from the spectral-element dy-
namical core with those produced by the default nite-volume dynamical core and with observations.
