CAM is the official atmospheric component of the NCAR Earth System Model and in its version 5 (Neale et al., 2012) it is also the atmospheric component of the new CMCC coupled climate model (CMCC-CESM-NEMO) and of the new Earth System Model under development (CMCC-ESM). Over the last 20 years, NCAR scientists provided a comprehensive, three-dimensional global atmospheric model with continuous updates and new implementation available to the whole scientific community.

CAM is available at different horizontal representation (i.e. spectral, finite volume) and at different horizontal resolutions. Since the first version, the complexity of the parameterization included has increased constantly. For example, its most recent version enables the simulation of the full cloud-aerosols indirect radiative effects, while in previous versions different schemes of aerosols prescription where available.

At ODA division in the Earth System Modelling Unit, the stand-alone CAM model is in use for the production of high resolution (1/4) AMIP experiments to be used as forcing for global and regional oceanic re-analysis and to provide different physical modules at increasing complexity.
