  • VOC to NOx relationships and Impacts of Smoke on Ozone in the Wasatch Front

    To meet ozone standards in the Wasatch Front, this project analyzes the role of local and non-local emissions, especially from wildfires. Researchers will assess wildfire impacts on ozone and PM2.5 levels using satellite and in-situ data, and study ozone sensitivity to NOx and VOCs through formaldehyde-to-NO2 ratios. Insights from this work will inform emission reduction…

  • Temporal and Spatial Measurements of Surface-to-Boundary Layer Ozone using Uncrewed Aerial Systems (UAS)

    Using drones and portable ozone monitors, this research will capture detailed pollutant data near the Great Salt Lake to complement existing ground and airborne measurements. Coordinated with the Utah Summer Ozone Study (USOS), the project will gather crucial information on ozone and other pollutants to address research goals on ozone sources and vertical oxidant exchange.

  • Quantification of Halogen-Initiated Atmospheric Chemistry in the Wasatch Front

    Focused on the unique atmospheric chemistry of Salt Lake City, this study investigates the influence of regional halogen emissions on ozone and particulate matter. By measuring chlorine-induced reactions with volatile organic compounds, researchers will quantify the extent of halogen-driven oxidation. The findings will provide essential data on how regional industrial emissions contribute to air quality…

  • Projecting the impacts of a shrinking Great Salt Lake on dust exposure along the Wasatch Front

    This project examines the dust exposure risks from the receding Great Salt Lake, using models to simulate dust emissions and transport across the Wasatch Front. It will evaluate the impact of different water levels on dust exposure, providing Utah DAQ with data to determine dust source contributions and identify communities at risk.

  • Improving Soil NOx Emission Estimates for the Wasatch Front

    This study examines the impact of soil nitrogen oxide (NOx) emissions on air quality in the Northern Wasatch Front, with a focus on refining NOx emissions modeling. By updating inputs in the Berkeley-Dalhousie Soil NOx Parameterization (BDSNP) for the MEGAN biogenic emissions model, the project aims to improve NOx emission estimates. Results will enhance understanding…

  • Assessing Global Background Ozone Transport Pathways to the Northern Wasatch Front

    This project uses high-resolution modeling to explore how international and regional ozone is transported into the Northern Wasatch Front. By analyzing vertical transport patterns, the study will provide a mechanistic understanding of ozone levels in the area, supporting regulatory planning. The findings are crucial for refining air quality models and informing future policy demonstrations.
