Abstract at Time of Award

This project will investigate the role of chlorine (Cl) in atmospheric chemical processes in the wintertime Arctic. A measurement campaign will be conducted at Oliktok Point Alaska, a field site that is operated by the U.S. Department of Energy’s Atmospheric Radiation Measurement Program (DOE ARM) and is located in the vicinity of the north slope of Alaska oilfields. Atmospheric Cl emitted from wintertime saline snowpacks can react with volatile organic compounds (VOCs) emitted from the oil fields to form secondary organic aerosol (SOA). The importance of this process will be evaluated and the results may have application to other coastal, snow-covered, polluted locations around the world. This study will include the following: (1) SOA molecular characterization utilizing state-of-the-art mass spectrometry; (2) coupling mass spectrometer measurements to an oxidation flow reactor (OFR) to facilitate investigation of aerosols produced from mixtures of biogenic VOCs with anthropogenic VOCs, sulfur dioxide, and nitrogen oxides; (3) intensive studies to investigate the effect of substantially different hydroxyl radical (OH) concentrations and residence times between OFRs and environmental chambers; and (4) measurements of the phase state, hygroscopicity and optical properties of different types of relevant seed particles coated with SOA to better understand the associated properties of complex ambient organic-containing particles and their representation in climate models. This project was supported under the NSF Grants for Rapid Response Research (RAPID) program because the U.S. Department of Energy has announced that the Oliktok Point field site will be closing in 2021, with the removal of complementary atmospheric measurements starting in the fall of 2020. There are no plans to reopen this site; thus, there is an urgent need to conduct the research at this site before it is closed. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
