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 stations deployed by the Utah Division of Air Quality, the University of Utah, and the PurpleAir citizen-science networks. Additionally, monitors deployed on UTA TRAX light rail cars, vehicles, and KSL-TV Chopper 5 may also be available.

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 from the Utah Division of Air Quality and MesoWest networks (squares) and the PurpleAir network (triangles). Marker color is based on observation value according to the legend on the map.

Weather observations from of the MesoWest 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.
