Kroll, Murakami, and Seneviratne Receive 2013 James B. Macelwane Medals: Citation for Jesse H. Kroll

Jesse H. Kroll, Motohiko Murakami, and Sonia I. Seneviratne were awarded the 2013 James B. Macelwane Medal at the AGU Fall Meeting Honors Ceremony, held on 11 December 2013 in San Francisco, Calif. The medal is for “significant contributions to the geophysical sciences by an outstanding early career scientist.”



Jesse Kroll is playing a leading role in unraveling the extremely complex multiphase atmospheric chemistry of organic molecules emitted by both anthropogenic activities and biogenic processes. His work is particularly important because atmospheric organic species form a large fraction of airborne submicron particulate matter (PM), which is responsible for most of the adverse human health effects, including premature mortality, attributed to poor air quality. Submicron aerosol PM also drives important direct and indirect impacts on atmospheric radiative transfer, causing much of the uncertainty in our understanding of current, and predictions of future, climate change.
