This page provides access to air quality observations that have been collected since 2014 by a variety of different resources. Included are fixed-site monitors deployed by the Utah Division of Air Quality, the University of Utah, Meteorological Solutions Inc., and the PurpleAir citizen-science network. Additionally, monitors deployed on UTA TRAX light rail cars, vehicles, and KSL-TV Chopper 5 may also be available at times.

Weather observations from of the Synoptic Data API Services can be plotted by clicking the "Load Weather Obs" button above the map. Observations will be plotted in wind barb format similar to MesoWest. Red numbers indicate temperature in degrees Celsius. Green numbers indicate relative humidity. Wind barbs show wind speed in meters per second (one full barb is 5 meters per second). Wind gust values larger than 5 meters per second are also shown in yellow if available.
The table below provides the last ozone concentration observation collected from each platform available on the map for the time period selected, with links to time series graphs available as well to show data over the previous 24 hours. Rows can be sorted by clicking on the table headers.
