Utah’s populated Wasatch Front, which includes the cities of Provo, Salt
Lake City, and Ogden, is affected by poor air quality during both the summer
and winter. In the summer, high ozone (O3) concentrations are often
observed, while during the winter high levels of particulate matter (PM2.5)
pollutants accumulate within the stagnant boundary-layer. Along the Wasatch
Front urban environment, considerable spatial and temporal variability in
pollutant concentrations is observed, resulting from the varying impacts of
four key factors: 1) complex terrain, 2) local flows, 3) vertical stability,
and 4) local pollutant emissions. In this study, we summarize the spatial
and temporal variability in wintertime and summertime pollutant
concentrations as observed during 2015 and 2016 from three mobile instrument
platforms: Two Utah Transit Authority (UT) light rail trains and a breaking
news helicopter.
