Ozone patterns along the Wasatch Front based on time of day. Understanding these spatial patterns can increase your air-quality awareness and help you plan your daily activities to reduce your exposure to air pollution. These factors combine to create gradients in air quality across the city that differ by season and time of day. The spatial patterns of air pollution are controlled by emissions, atmospheric chemistry, and daily wind patterns. This project, along with several other innovative projects (such as low-cost PM 2.5 networks from PurpleAir and AQ&U ) as well as the gold standard for air-quality measurements from the Utah Department of Environmental Quality (DEQ) Division of Air Quality (DAQ), have dramatically increased the spatial coverage of air-quality measurements along the Wasatch Front and are leading to new insights into our air-pollution patterns. We’ve been measuring particulate matter ( PM 2.5), ozone ( O3), and nitrogen dioxide ( NO 2), as well as the greenhouse gases carbon dioxide ( CO 2), and methane ( CH 4). But did you know that the train you’re riding on may also be helping scientists study air pollution along the Wasatch Front?įor the past few years, my colleagues and I at the University of Utah have partnered with the Utah Transit Authority (UTA) and installed air-pollution monitors on two TRAX trains that operate on the Red and Green TRAX lines. One great way you can help to reduce emissions and improve air quality is by using public transit. TRAX train sporting an air-quality monitor on top Utah Air Quality Rulemaking Actions Notices. Centralized Air Emissions Reporting System.Existing Applications, Draft Permits, and Permits.
