  • TRAX Air Quality Observation Project (Blue Line)

    The TRAX air quality project continues to measure PM2.5 and ozone from TRAX light rail trains, and will add measurements to the Blue line. All data is publicly available and posted in near real-time on the MesoWest website. Principal Investigators: Daniel Mendoza, Logan Mitchell, John Horel, John Lin (UU) Funded by legislative appropriation: $44,000

  • Investigating Sources of Ammonia Uncertainty in Modeling the Salt lake City PM2.5 Nonattainment Area

    This study will investigate the existing emission inventory of ammonia (NH3) sources and compare modeled NH3 concentrations to those observed during recent field studies in order to identify and correct missing NH3 sources. In addition to improving the inventory, this study will add new NH3 emission pathways to the photochemical model. Principal Investigators: Chris Emery…

  • The Red Butte Canyon Air Mass Exchange and Pollution Transport Study

    The University of Utah will make measurements of vertical wind and aerosol profiles, as well as ozone and fine particulate matter (PM2.5) concentrations at the mouth of Red Butte Canyon in order to better understand air exchange in the Salt Lake Valley during wintertime PM2.5 events. Principal Investigators: Sebastian W. Hoch, Erik T. Crosman (UU)…

  • The Red Butte Canyon Ozone Network:
    Leveraging Existing Infrastructure to Probe Background Concentrations, Canyon Flows, and Stratospheric Oxidant Exchange

    This study will deploy a number of ozone sensors at different distances up Red Butte Canyon to better understand natural gradients in ozone and how phenomena like large thunderstorms and valley drainage flows contribute to ozone concentrations in the Salt Lake Valley. Principal Investigators: Logan Mitchell, Ryan Bares, David Eiriksson (UU) Funded by Science for…

  • Understanding How Wood-Burning’s Contribution to Particulate Matter Concentrations Have Changed over Time

    Wood burning contributes to fine particulate matter (PM2.5) pollution in the Wasatch Front, and reducing the use of wood burning during pollution episodes has been the focus of many policy decisions. This study looks at patterns of temperature, heat deficit, and day of the week along with markers of woodsmoke and mandatory no-burn days, to…

  • Smoke School: Training Schedules

    The State of Utah no longer furnishes a Visible Emissions Course (Smoke School) but that function has been taken up by the private sector

  • Health Impacts of Wildfire Smoke

    Wildfire smoke can make outdoor air unhealthy to breathe. Even if you stay indoors, some of the smoke from outdoors can enter your home. If you are close to a wildfire, the fire itself, as well as heavy smoke and ash, can pose serious, immediate risks to your safety and health. You may also be…

  • Protect Yourself From Wildfire Smoke

    Wildfires create smoky conditions, but there are things you can do– indoors and out–to reduce your exposure to smoke. Children (498 KB), older adults, and people with heart or lung disease are particularly susceptible to the health impacts of wildfire smoke, but it can also pose risks to healthy adults. Reduce Smoke Exposure Outdoors If…
