An overview of the 2015 Great Salt Lake Summer Ozone Study

Researchers from several universities in Utah and the Utah Division of Air Quality studied the distribution of boundary-layer ozone and concurrent meteorology during summer 2015 in the vicinity of Utah's Great Salt Lake referred to as the 2015 Great Salt Lake Summer Ozone Study (GSLO3S). The GSLO3S aims to determine the areal and vertical extent of ozone concentrations over and surrounding the Great Salt Lake during the summer, and improve understanding of the physical processes that control ozone concentrations near the Great Salt Lake during the summer to improve forecasts of ozone concentrations along the Wasatch Front. Concentrations at Badger Island rarely dropped below 30 ppb at night, indicating limited ozone titration, likely due to its distance from nocturnal urban emission sources. However, titration at Farmington Bay led to ozone concentrations below 20 ppb during most nights with a greater number of afternoon peaks above 70 ppb during June, early July, and August as compared to the more remote Badger Island.
