CESM Polar Climate Working Group

The Polar Climate Working Group (PCWG) is a consortium of scientists who are interested in modeling and understanding the climate in the Arctic and the Antarctic, and how polar climate processes interact with and influence climate at lower latitudes. Our members come from universities and laboratories, and our interests span all elements of polar climate, from the ocean depths to the top of the atmosphere. In addition to conducting scientific modeling experiments, we are charged with developing and maintaining the state-of-the-art sea ice model component (CICE) used in CESM. Although the Land Ice Working Group is responsible for modeling land ice (glaciers, ice sheets), LMWG and PCWG members are interested in these processes also. Workshops and meetings of the PCWG are open to all who are interested in polar processes. If you wish attend future meetings of the PCWG, please contact the community liaison, David Bailey, or either of the co-chairs.

The PCWG also develops and maintains a standard set of diagnostic plots for quick look at the sea ice simulation from the CESM. These include timeseries, contour, and vector plots with annual, seasonal, and regional means. The plots are compared to observations where available. A sample of the current plots is available at: 2-degree Pre-Industrial Control. This sea ice diagnostic package is freely available from the CESM Subversion release repository at: CESM Sea Ice Diagnostic Package. Note that a one-time registration is required to access the release repository: CESM 1.0 Release Page.

Online materials from the CESM Tutorial, including lectures and practical sessions on the CESM sea ice component, are available after a short registration: CESM Tutorials including online materials.

Research Highlights

Some current research from the PCWG is available at: Research Highlights. Also, several PCWG papers are included in the CCSM4 special issue of the Journal of Climate and will appear at: CCSM4 Special Collection.

Some members of the PCWG have drafted some documents on observational needs for climate models in the polar regions. The first one is intended to be a living document and feedback is appreciated.

    CESM Project

    The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.

    CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR).
