Atmosphere Model Working Group (AMWG)

The Atmosphere Model Working Group (AMWG) is a broad collection of researchers across university and federal institutions engaged in atmospheric science research using the Community Earth System Model (CESM). The overarching goal is to continually develop the Community Atmosphere Model (CAM) in order to periodically provide new versions for use by the wider CESM community.

We set short and long term development targets to guide community research. Ultimately, we aim to deliver the best representation of the atmosphere to be used in multiple applications for climate, climate variability and climate change research.

Featured AMWG Articles

CAM Development

Development focuses on research into new and existing physical parameterizations, dynamical cores and added functionality for CAM.

Dycores & resolution

Current research focuses on a new vertical grid for CAM with increased resolution & higher model tops, exploring the benefits of increased horizontal resolution both globally & in regionally-refined configurations, and implementing three potential dynamical cores.

Parameterizations

Current efforts focus on improved representation of moist turbulence and convection from planetary boundary layer (PBL) processes to organized mesoscale convection
