MesoWest Utah Air Quality Data - Time Series Interface

This page provides access to time series plots of air quality observations that have been collected from various resources across Utah. Included are fixed-site monitors deployed by the Utah Division of Air Quality, the University of Utah, and others. Additionally, monitors deployed on UTA public transit systems, other vehicles, and KSL-TV Chopper 5 may also be displayed.

Time Options: Year: Month: Day: Hour: Minute: Timezone: Period:

Two plots can be generated using the time information above, enter station IDs and select variables to plot here. Keep in mind not all stations report the same measurements, so some plots may not load or appear blank if data is not available for the station selected.

Plot 2: Station: Left: Right (mobile only):



*Note: The particulate observations shown here are from a wide variety of sensors, each with their own strengths and weaknesses. Some sensors (deployed on the mobile platforms and some fixed sites) can occasionally record higher values when the air contains a lot of PM2.5 as well as excess moisture (such as dense fog).

On the map above, square markers are primarily fixed-site observations made available courtesy of data aggregation services by Synoptic Data PBC. Triangle markers represent low-cost sensors from previously-available resources such as PurpleAir and AirU. Circle markers represent data collected from mobile platforms managed by the University of Utah Department of Atmospheric Sciences. The larger markers represent the most recent observation for the time period, with trailing transparent markers representing older observations.
