Administration of the Community Climate System Model

The CCSM Advisory Board (CAB) will serve as an advisory committee reporting to the CCSM Scientific Steering Committee, NSF Program Director, NCAR Director, and UCAR President. Membership in the CAB will come from university faculty and staff, staff members of national laboratories, and scientists from foreign universities, laboratories, and centers.

The Scientific Steering Committee (SSC) will provide scientific leadership for the CCSM project, including oversight of activities of working groups, coordination of model experiments, decision making on model definition and development.

The detailed work on various aspects of CCSM will be done in working groups. These working groups will consist of scientists who come together to work on topics on which they share common interest.

CESM Strategic Plan

Over the past five years the Community Climate System Model (CCSM) has increased in scope to a Community Earth System Model (CESM) by including an interactive carbon cycle component, an interactive chemistry component, a whole atmosphere component (dynamics and chemistry of the stratosphere and mesosphere), and a new land-ice component. Three new working groups have been formed to develop the chemistry, whole atmosphere and land-ice components. The project also works continuously to improve the simulations of the basic physical model, because reduced biases are required when these new components are added. [Statement to NSF]
