How to make sense of air quality data

What is AQI (Air Quality Index)?

AQI is the EPA's index for reporting air quality. Higher AQI values indicate greater air pollution and associated health concerns.

AQI and PM2.5:

This map shows Fine Particulates (PM2.5), which are a key air quality metric used to calculate the AQI. Some are emitted directly from sources, such as construction sites, unpaved roads, vehicle emissions, smokestacks, fires, and other combustion sources. A large fraction of particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide, volatile organic compounds, and nitrogen oxides, which are pollutants emitted from power plants, industries, and automobiles.
Other primary pollutants in AQI calculations include course particulates (PM10), ozone, nitrogen dioxide, and sulfur dioxide.

Raw Data Sources:

Raw air quality data is aggregated from various public air quality monitors throughout the State of Utah. Sources include PurpleAir, EPA, and TELLUS. Rigorous screening, calibrations, and modeling are provided by TELLUS CoreDI to ensure high-quality actionable air quality data that empowers informed decisions about air quality for community members.

TELLUS CoreDI:

Core Data Intelligence (CoreDI) is a tightly integrated hardware-software ecosystem. It employs machine-learning-based spatial and temporal interpolation to ensure reliable air quality data continuity across multiple sources and the space between the sources themselves. Learn more
