AQI or Air Quality Index is the primary way to measure the current quality of the air. AQI values range from 0-500 with 0 being perfectly healthy and 500 being extremely hazardous. AQI values are derived from moving averages/current values of PM2.5 (particulate matter), PM10, Ozone, Carbon Monoxide, Sulfur Dioxide, and Nitrogen Dioxide levels. This dataset was created using Locational Data from: https://simplemaps.com/data/us-cities and AQI Data from: https://aqs.epa.gov/aqsweb/airdata/download_files.html. The dataset then became available here.With this dataset, we can look at what areas are the most dangerous, how the air quality changes over time, and how an areaâ€™s pollution levels change over time.
