Overview
The Community Earth System Model (CESM) has its roots in the early 1980s, when the National Center for Atmospheric Research (NCAR) began developing the Community Climate System Model (CCSM). The CCSM was a significant step forward in climate modeling, but it had limitations. CESM built upon the foundation of CCSM, incorporating new components and capabilities, such as the Whole Atmosphere Community Climate Model (WACCM) and the CESM-Large Ensemble (CESM-LE) forecasting system. The development of CESM was a collaborative effort, with contributions from researchers and institutions worldwide, including the National Science Foundation (NSF) and the University Corporation for Atmospheric Research (UCAR).
⚙️ How It Works
The Whole Atmosphere Community Climate Model (WACCM) is a key component of CESM. CESM has been used to study a wide range of topics, including climate change, ocean currents, and the carbon cycle. CESM's simulations have been validated against observational data, demonstrating its accuracy and reliability. The model's strong ensemble forecasting capabilities, CESM-LE, allow researchers to control for error and biases across different model runs (realizations).
📊 Key Facts & Numbers
CESM has a number of key features and capabilities. The model has been used to study various aspects of the Earth's climate, including climate change, ocean currents, and the carbon cycle. CESM's simulations have been used to inform environmental policy decisions, such as the development of renewable energy sources and the implementation of carbon pricing mechanisms. For example, CESM has been used to study the impact of climate change on sea level rise and the water cycle.
👥 Key People & Organizations
The development and maintenance of CESM involve a number of key people and organizations, including the National Center for Atmospheric Research (NCAR) and the National Science Foundation (NSF). The National Oceanic and Atmospheric Administration (NOAA) and the University Corporation for Atmospheric Research (UCAR) also contribute to CESM's development and maintenance. Researchers from around the world use CESM to study the Earth's climate and its complex systems, including James Hansen and Katherine Hayhoe.
