CESM Working Groups

Office space

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

Science Liaison: Cecile Hannay

Software Liaison: None at this time

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.

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.

BGCWG | Biogeochemistry

Science Liaison: Keith Lindsay

Software Liaison: None at this time

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

PWG | Paleoclimate

Science Liaison: None at this time

Software 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.

CCWG | Chemistry Climate

Science Liaison: Simone Tilmes

Software Liaison: None at this time

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.

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.

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.

SDWG | Societal Dimensions

Science Liaison: None at this time

Software Liaison: None at this time

SDWG enhances CESM and its application to improve understanding of the interactions between human and earth systems.

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.

SEWG | Software Engineering

Science Liaison: Alice Bertini

Software Liaison: None at this time

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.

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.

WAWG | Whole Atmosphere

Science Liaison: Michael Mills

Software Liaison: None at this time

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