infoDefinitions

The Annual Air Quality Index is a summary measure of overall air quality for the year. In order to be in compliance with the Environmental Protection Agency's ground-level ozone standard, a location should have a 3-year average of fewer than 76 parts per billion (ppb). This standard is based on the presence of harmful ozone (O3) molecules outside the ozone layer in the stratosphere.
