AbstractThis research will focus on advancing the understanding of particle acidity in the atmosphere of cold environments and assessing the effects of fuel oil sulfur reductions on particulate sulfur and other species in Alaskan cities. A recent transition to lower-sulfur fuel oil as part of a government-mandated air quality mitigation strategy in Fairbanks and neighboring communities offers a rare opportunity to directly observe and quantify the atmospheric impacts of reduced sulfur emissions.
