    * Although preliminary annual statistics are continually released, SAGE Stats only provides final statistics, which are released in May of the following year. Report includes exceptional events; these events (such as wildfires) are not "reasonably controllable" and are hence excluded from assessments relating to air quality regulation, but they nevertheless affect air quality.

    Years Available: 2000–2016
