A primary NCAR activity is creating models that enhance human understanding of the atmosphere, the Earth system, and the Sun. Our efforts help scientists worldwide to better understand—and continually refine their knowledge of—how the Earth’s systems work. Other interested parties, such as national and regional leaders, also use this information to make decisions on scales ranging from local to international. Relying on complex mathematical descriptions of real-world phenomena, scientists can compare Earth system model results against real-world observations to more effectively take appropriate action, whether scientific or policy related.
The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs.
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.
The Whole Atmosphere Community Climate Model (WACCM) is a comprehensive numerical model, spanning the range of altitude from the Earth's surface to the thermosphere.
