Atmosphere Model


Welcome to the AMWG webpage.

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.

The AMWG sets short and long term development targets to guide community research. Development focuses on research into new and existing physical parameterizations, dynamical cores and added functionality for CAM. To this end close interactions exist with the Chemistry-Climate Working Group (Chem-ClimWG) and the Whole Atmosphere Working Group (WAWG). 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.


Community Atmosphere Model (CAM)

The Community Atmosphere Model (CAM) is the latest in a series of global atmosphere models developed at NCAR for the weather and climate research communities. CAM serves as the atmospheric component of the Community Earth System Model (CESM).

CAM simulations and analysis

We provide data and diagnostics for a set of CESM and CAM experiments. We also provide tools to analyze the model output.


CAM development and Development Documents

  • CAM Model Development
    This page is intended to be a summary of the AMWG activities in developing the Community Atmosphere Model version 6 (CAM6).

  • CAM development protocols
    This page summarizes the guidelines and protocols used in developing CAM6.

  • AMWG Simulation Metrics
    This page summarizes the metrics and diagnostics used in developing CAM6. We request the AMWG input on current metrics (top 10 quantities) and other potential quantities.
