The Alaskan Layered Pollution and Chemical Analysis (ALPACA) Project

Résumé

Wintertime air pollution is a common problem in Arctic cities and nearby industrial locations. Cold temperatures often lead to large emissions from heating and transportation, and these emissions are commonly trapped by strong meteorological inversions leading to poor ground-level air quality. To improve air quality, we need better understanding of these emissions, how they chemically react to form secondary pollution, and how they mix and disperse. Until recently, few air quality field campaigns have focused on wintertime conditions, and none of these campaigns have addressed the extreme meteorological and low-photochemical conditions of Arctic and sub-Arctic locations like Fairbanks, Alaska. Therefore, we initiated an effort under the "air Pollution in the Arctic: Climate, Environment, and Societies" (PACES) that identifies key unknowns and designs a field experiment to improve understanding of these unresolved questions. In this presentation, we report on the ALPACA workshop, which was held in May 2018 and the development of a whitepaper that identifies unresolved questions and designs the ALPACA field campaign. We welcome community involvement in this project and hope that its findings will improve air quality for Arctic residents.
