Read MoreHigh wintertime ozone concentrations are relatively new phenomena in rural areas of the West. First observed in 2005 in the oil and gas production areas in the Upper Green River Basin (UGRB) of Wyoming, preliminary studies showed that wintertime ozone levels would spike when snow cover, sunny skies, and strong temperature inversions trapped ozone and …
Read MoreStarting in the winter of 2012, the Uinta Basin Ozone Study (UBOS) launched a wide-ranging research effort into the ways atmospheric chemistry and precursor gases interact to create high levels of wintertime ozone. The study was by far the largest and most complex air quality study ever conducted in Utah. This effort was funded by …
Read MoreTeams of scientists continued their work in the Uinta Basin in 2013 to identify the sources and conditions that create ozone during winter inversions. The Division of Air Quality (DAQ) and its partners collected additional data to improve their understanding of the atmospheric chemistry that leads to the formation of wintertime ozone in the Basin. …
