Fourth Annual CSM Workshop Announcement

Breckenridge, Colorado - June 22-24, 1999

The National Center for Atmospheric Research (NCAR) is continuing to develop the state-of-the-art Climate System Model (CSM) for community applications. The project is coordinated by a Scientific Steering Committee consisting of both NCAR and non-NCAR scientists.

The present CSM consists of atmospheric and oceanic general circulation models, a land surface biophysics model, and a sea-ice model. The model components are connected by a mass and energy conserving "flux coupler" that also allows flexibility in the spatial resolutions of the component models and straightforward implementation of alternate components. A Climate of the 20th and 21st Century simulation, a multi-hundred year paleoclimate simulation, and a 300-year run with an accurate simulation of the present climate with very little drift in surface temperature fields have been completed.

The 1999 CSM workshop is scheduled at the same conference center as last year, The Village at Breckenridge, from Tuesday, 22 June 1999, to Thursday, 24 June 1999, in Breckenridge, Colorado. A draft agenda is in progress. The workshop is open, but space is limited. Therefore, anyone interested in attending the workshop must send in a registration form before Friday, 30 April 1999. Registration forms can also be mailed or faxed if necessary. All participants MUST register, although registration may not guarantee attendance depending on availability of space. Limited travel funds may be available, and the registration form should indicate details of any financial requirements needed and also your previous participation in the CSM project.

The CSM project has been developed under National Science Foundation (NSF) and inter-agency sponsorship as part of the U.S. Global Change Research Program.
