Working Groups

AMWG | Atmosphere Model Working Group

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.

  • CESM Experiments, Data and Diagnostics
  • CAM Experiments and Diagnostic Output (coming soon)
  • The AMWG diagnostics package is a post-processing utility for CAM. It produces over 600 plots and tables from CAM monthly output and automatically create webpages. This utility is currently provided as a service to the community.
  • NCL is a free interpreted language designed specifically for scientific data processing and visualization.
