Outdoor Air Quality Sensors at all TCSD schools

Each sensor measures a variety of harmful airborne particulates such as smoke, soot and a common pollutant known as PM2.5. Schools can use results from the sensors to determine if students should stay inside for recess to avoid inhaling potentially harmful air.

During winter months when temperature inversions are common, air quality is more likely to be poor. Inversions are caused when warm air traps cold air and pollutants beneath it.

With winter fast approaching the school district is pushing to have elementary school sensors installed first since younger children are more susceptible to problems linked to raised levels of particulates.

Overlake Elementary was the first school to have a sensor installed thanks to a donation from KSL last school year during a visit from Meteorologist Dan Guthrie. TCSD Superintendent Scott Rogers liked the concept and wanted to ensure each school had the ability to monitor air quality for students and staff. Since then, TCSD has purchased outdoor air quality sensors for each school and the district office.

The community can track data from the installed sensors by going to the PurpleAir map: https://www.purpleair.com/map#11.24/40.5739/-112.4236

“The PurpleAir Map displays the points using the Federal Environmental Protection Agency Air Quality Index scale. The AQI allows comparison for different pollutants with an easy to visualize color scheme. The air goes from good green air to yellow to orange to red to purple air, or even hazardous maroon air. The graphs give further information on different counts, relative weights and sizes of particles in the air.” (https://www.purpleair.com/faq)
