Richmond, IN Air Quality

EPA monitor data through 2016 · Updated September 04, 2026 · Methods

This area's record ends with 2016: EPA's air quality files carry no 2017–2025 data for it, usually because local monitors stopped reporting. This page is current with the data that exists.

In 2016, Richmond, IN recorded 0 days above an Air Quality Index of 100, the level at which EPA begins warning sensitive groups, out of 366 days with monitoring data. Under the AQI rules that applied before 2013, the same air would have scored 0 days.

Unhealthy days by year, scored two ways

EPA changed what an AQI of 100 means in 2013 and again in 2015, so a count published before those changes is not comparable to one published after. Each panel below applies a single fixed rulebook to every year, so each is internally consistent. Why this matters.

Days in each air quality category, by year

How many days fell in each AQI category, for every year with an AQI on record. Categories are scored under EPA's current breakpoints. A year with fewer than 300 days is marked, because a short year lowers every count for reasons that have nothing to do with the air.

YearGoodModerate Unhealthy for sensitive groupsUnhealthy or worse Days with an AQI
2000 (partial) 5900 059
2001 (partial) 6100 061
2002 (partial) 5100 051

Good is AQI 0–50, Moderate 51–100, Unhealthy for sensitive groups 101–150. “Unhealthy or worse” combines the Unhealthy, Very Unhealthy and Hazardous categories, which are shown together because most areas record too few of each to report separately. The four columns sum to the last one by construction. 14 years with monitoring but no AQI are omitted. These counts exclude sulphur dioxide, following EPA, which drops SO₂ from county and metro summaries because it is too localized to describe a whole area.

The full series

The same years scored two ways, with the pollutant that drove the days above 100. EPA's files record which pollutant set each day's AQI; they do not attribute days to wildfire smoke, so no column here claims to.
