2012: CESM Distinguished Achievement Award

Bill Lipscomb is the recipient of the 2012 CESM Distinguished Achievement Award. Bill's contributions to the CESM project began over ten years ago when he joined the Climate, Ocean and Sea Ice Modeling (COSIM) team at Los Alamos National Laboratory as a Postdoctoral Researcher. In his initial years at Los Alamos, Bill made notable improvements to the Los Alamos sea ice model, which is the sea ice component of CESM. In more recent years, Bill has established and led the effort to incorporate a land ice component into CESM. Through Bill's inventive and hard work in this area, the CESM project is now making exciting contributions to our understanding of ice sheet loss and sea level rise. [more]

2011: CESM Distinguished Achievement Award

David Williamson is the recipient of the 2011 CESM Distinguished Achievement Award. David Williamson is long overdue recognition for his significant contributions to CESM and community modeling at NCAR. His science contributions are particularly noteworthy as more often than not they were breakthrough, innovative research activities for global modeling in general and not just for CESM. Dave is one of the pioneers of the present-day discretization methods for the atmospheric primitive equations used in CESM. He was also heavily involved in addressing the problems of discretization on a sphere exploring the use of geodesic or hexagonal grids. [more]

NCAR releases CESM1.0

The Community Earth System Model: NCAR's latest step in the quest to model Earth's climate. 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. The improvements in the new software release "gives a better representations of the real world" says James Hurrell, CLIVAR co-chair and chair of the scientific committee that developed the model.

NCAR releases version 4 of CCSM

A completely upgraded and more advanced version of the Community Climate System Model (CCSM) became available to university and laboratory researchers with the release of CCSM4.0 on 1 April. Supported primarily by NSF and the U.S. Department of Energy, CCSM4 is a state-of-the-science tool that allows scientists to explore the history of Earth’s climate, investigate processes and mechanisms responsible for current climate variations and change, and estimate future states of the climate system to guide adaption strategies and policy formulation.

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 Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).
