The NASA ARCTAS aircraft mission was conducted in spring-summer 2008 to investigate the sources, transport, and chemical evolution of Arctic pollution, the implications for radiative forcing of climate, and the role of boreal forest fires. I will present results from ongoing work at Harvard to interpret the ARCTAS observations for better understanding of Arctic atmospheric composition. Topics will include (1) long-range transport of pollution, (2) sources, composition, and evolution of the aerosol, (3) radical photochemistry, (4) sources of methane, and (5) sources and fate of mercury.
Bio Sketch
Daniel J. Jacob is the Vasco McCoy Family Professor of Atmospheric Chemistry and Environmental Engineering in the School of Engineering & Applied Science at Harvard University. He has a B.S. (1981) in Chemical Engineering from the Ecole Supérieure de Physique et Chimie de Paris, and a Ph.D. (1985) in Environmental Engineering from Caltech. He joined Harvard in 1985 and has remained there ever since. His research interests cover a wide range of topics in atmospheric chemistry, involving in particular the development of global models of atmospheric composition. Jacob has served as Mission Scientist on six NASA aircraft missions. Among his professional honors are the NASA Distinguished Public Service Medal (2003), the AGU Macelwane Medal (1994) and a Packard Fellowship for Science and Engineering (1989). Jacob has published over 270 papers and trained over 60 Ph.D. students and postdocs over the course of his career. He is the 6th most-cited author in geosciences according to the ISI Science Citation Index.
