CCR leaders awarded Department of Energy funding to study connection between aerosols and historical climate variability

Leaders from the Nelson Institute Center for Climatic Research (CCR) will begin investigating the role of clouds and aerosols (small particles in the atmosphere, such as sulfate or dust) in historical climate variability thanks to support from the Department of Energy. While previous Earth System Models indicate that aerosols influence variations in surface temperature and precipitation processes, this research is the next step in enhancing predictive and process level understanding of how clouds and aerosols impact climate variability in the North Atlantic and the Pacific.

The study will be led by Daniel J. Vimont, CCR director and a professor of Atmospheric and Oceanic Sciences and Tristan L’Ecuyer, professor of Atmospheric and Oceanic Sciences and director of the Cooperative Institute for Meteorological Satellite Studies, with assistance from Salil Mahajan, a climate computational scientist with the Oak Ridge National Laboratory.
