The Lake Michigan Ozone Study 2017 (LMOS 2017) was a collaborative multiagency field study targeting ozone chemistry, meteorology, and air quality observations in the southern Lake Michigan area. The primary objective of LMOS 2017 was to provide measurements to improve air quality modeling of the complex meteorological and chemical environment in the region. LMOS 2017 science questions included spatiotemporal assessment of nitrogen oxides (NO = NO + NO) and volatile organic compounds (VOC) emission sources and their influence on ozone episodes; the role of lake breezes; contribution of new remote sensing tools such as GeoTASO, Pandora, and TEMPO to air quality management; and evaluation of photochemical grid models.

- The Lake Michigan Ozone Study 2017 (LMOS 2017) focused on understanding ozone pollution in the Lake Michigan region through various sampling methods, including ground-based, airborne, and maritime approaches.
- Two key sampling sites in Zion, Illinois, and Sheboygan, Wisconsin, were chosen for their unique positions to study both less processed and aged air parcels during high-ozone events.
- The results indicated significant ozone concentrations during several multi-day periods, with local vehicle traffic and large point sources contributing minimally (under 15%) to the pollution levels, leading to discussions on future research methods and model comparisons.
Article Synopsis
- The study uses airborne measurements across different seasons to analyze methane emissions in the US Corn Belt and Upper Midwest, focusing on natural and anthropogenic sources.
- It finds that wetlands are the largest methane source, while livestock contribute significantly as the major human-related source, with implications for emission management.
- The research highlights discrepancies in methane estimates from different agricultural practices and suggests improvements in management strategies for livestock to effectively mitigate emissions.
