The Whole Atmosphere Community Climate Model (WACCM) Working Group meeting will be held February 1, 2012 in Boulder, Colorado. As a comprehensive numerical model, WACCM spans the range of altitude from the Earth's surface to the thermosphere. The development of WACCM is an inter-divisional collaboration that unifies certain aspects of the upper, middle, and tropospheric models using the Community Earth System Model (CESM) as a common numerical framework. The meeting meeting agenda is now available.
