Abstract Short-lived chemical compounds in the atmosphere--including gases such as ozone and its precursors, and aerosols such as sulfate and black carbon-- are important for air quality as well as for climate. Distributions of these chemical compounds are modulated by climate variability and change.  The emissions, transport, transformations, and removal processes important for controlling the distributions of ozone and aerosols will be described. Global chemistry-climate models will be introduced, along with results from these models and their evaluation using various observational datasets. Examples of the interactions between chemical composition and climate will be presented.
Bio:  Dr. Larry Horowitz is an atmospheric chemist at the NOAA Geophysical Fluid Dynamics Laboratory (GFDL), where he leads the Atmospheric Chemistry and Climate group. He is also a lecturer in the Atmospheric and Oceanic Sciences program at Princeton. He develops numerical models of atmospheric composition and applies them to study atmospheric chemistry, air quality, long-range transport of air pollution, and interactions of chemistry with climate and the biosphere.  He received his Ph.D. from the Division of Applied Sciences at Harvard University in 1997, and was then a postdoctoral fellow at the National Center for Atmospheric Research (NCAR) in Boulder, CO. He has been a scientist at Princeton and GFDL since 1999.
