"The primary goal of the Community Earth System Model (CESM) project is to develop a state-of-the-art climate model and to use it to perform the best possible science to understand climate variability and global change. We will strive to build a CESM community of users who are interested in participating in this project."
Identify and model the physical, chemical, biological, and human components that govern the climate system; quantify the certainties and uncertainties in Earth-system feedbacks on timescales up to centuries and longer.
Reliable information on expected climate conditions and impacts is needed to better inform societal decisions. Climate variability and change is determined by the functioning of the Earth’s physical, chemical, biological, and human systems and the interactions among them. To further understand climate system behavior, it is critical to maintain CESM as a world-class, community-based, state-of-the science, and comprehensive Earth System Model. This requirement depends on the translation of fundamental research on climate system processes into new and better parameterizations. It also necessitates the evaluation of model simulation behavior against process knowledge, observations and proxies from the distant past to the present.
