CESM Working Groups

The CESM Working Groups are relatively small teams of scientists that work on individual component models or specific coupling strategies. Each team takes responsibility for developing and continually improving its component of the CESM consistent with the CESM goal of a fully-coupled model and with the CESM design criteria. Each team will decide their own development priorities and work schedules, consistent with the overall goals of CESM, and subject to oversight by the CESM Scientific Steering Committee (SSC).

AMWG | Atmosphere Model

Liaison: Cecile Hannay
The Community Atmosphere Model (CAM) is the atmosphere model component of the CESM. Information about running CAM as the atmospheric component of the CESM is found in the CESM1.0 release.

BGCWG | Biogeochemistry

Liaison: Keith Lindsay
This working group was started at the 3rd Annual CSM Workshop, June 1998, in Breckenridge Colorado.

CCWG | Chemistry Climate

Liaison: Simone Tilmes
The goal of the Chemistry-Climate WG is to continue the development of the representation of chemical gas and aerosol species in the CESM and to further our understanding of the interactions between chemistry/aerosol and climate.

CVCWG | Climate Variability & Change

Science Liaison: Adam Phillips
Software Liaison: Gary Strand
CVCWG goals are to understand and quantify contributions of natural and anthropogenically-forced patterns of climate variability and change.

LIWG | Land Ice

Science Liaison: Gunter Leguy
Software Liaison: Katherine Thayer-Calder
LIWG primary objectives are (1) to couple a well validated, fully dynamical ice sheet model to the CESM, and (2) to determine the likely range of decade-to-century-scale sea-level rise associated with the loss of land ice.

LMWG | Land Model

Science Liaison: Keith Oleson
Software Liaison: Erik Kluzek
The CAM | Community Land Model is the land model component of the CESM. Information on the latest version of CLM, including technical descriptions, user guides, and download instructions can be found on the CLM web page.

OMWG | Ocean Model

Science Liaison: Gustavo Marques
Software Liaison: Alper Altuntas
Primary goals include: support of specific science objectives of the CESM and maintaining a state-of-the-art ocean component for the CESM and conducting related, but curiosity-driven, research leading to new contributions to the CESM community.

PWG | Paleoclimate

Liaison: None at this time
PWG is a consortium of scientists interested in modeling and understanding past Earth climates, allowing a long-term perspective on Earth-system feedbacks.

PCWG | Polar Climate

Science Liaison: Alice DuVivier, David Bailey
Software Liaison: David Bailey
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.

SDWG | Societal Dimensions

Liaison: None at this time
SDWG enhances CESM and its application to improve understanding of the interactions between human and earth systems.

SEWG | Software Engineering

Liaison: Alice Bertini
SEWG was formed to examine software engineering issues related to creating and executing CESM model codes, and to recommend and help coordinate software engineering practices that will help the CESM project to achieve its goals.

WAWG | Whole Atmosphere

Liaison: Michael Mills
WAWG is a comprehensive numerical model, spanning the range of altitude from the Earth's surface to the thermosphere.
