Owen Brian Toon is a Professor in the Department of Atmospheric and Oceanic Sciences for which he was the founding Chair, and a Research Associate in the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder. He received an A. B. in physics at the University of California at Berkeley in 1969 and a Ph.D. in physics at Cornell University in 1975. He was a Research Scientist at NASA’s Ames Research Center from 1975 until 1997 when he moved to Colorado.
Brian’s research group studies radiative transfer, aerosol and cloud physics, atmospheric chemistry and parallels between the Earth and planets. Brian has helped conceive, develop and lead many NASA airborne field missions aimed at understanding stratospheric volcanic clouds, stratospheric ozone loss, the effects of aircraft on the atmosphere, and the role of convective and cirrus clouds in Earth’s climate system. He has been involved in numerous satellite missions for both Earth and the planets.
He has published more than 300 papers in refereed scientific journals, and is one of the most highly cited researchers in Geoscience.
