MesoWest Utah Air Quality Data - Map Interface

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.

To choose a different time period or different variables, please use the options given below.

Diamond markers represent data from available frieght trucks. Circle markers represent data from Utah Transportation Authority TRAX light rail cars and other mobile sources. Additional markers are fixed-site observations collected by MesoWest (available via the Synoptic Data API Services) from equipment operated by the Utah Division of Air Quality, Meteorological Solutions Inc., the University of Utah Department of Atmospheric Sciences (squares), AirU (triangles), and the PurpleAir networks (triangles). Marker color is based on the observation value according to the legend on the map.

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.
