Quantifying Contributions from Natural and Non-local Sources to Uintah Basin Ozone

By Huy Tran, Seth Lyman, Trang Tran, and Marc Mansfield, Bingham Entrepreneurship & Energy Research Center

Ozone in the lowest layer of the atmosphere (the troposphere) results in large part from human activity: Pollutants already present in the atmosphere are converted to ozone by the action of sunlight. However, there are also natural sources of ozone, such as wildfires and a phenomenon known as a "stratospheric intrusion," when strong vertical mixing pulls ozone from the stratospheric ozone layer down to the surface. Using the GEOS-Chem global chemical model, we have successfully demonstrated that a stratospheric ozone intrusion event occurred on June 8–9, 2015, which caused surface ozone in the Uintah Basin to exceed the 70-ppb national standard. We have also identified many other cases in which natural or non-local sources contributed a large portion of the surface ozone in the Basin, especially during spring and summer, although at levels not exceeding the national standard. The ability to distinguish human-caused local, human-caused non-local, and natural ozone events is important for planning and evaluating ozone mitigation strategies.
