122

Days with an AQI in 2020 (of 366)

In 2020, EPA reported a daily Air Quality Index (AQI) for Taney, Missouri on 122 days. 113 of those days (93%) were in the Good range, and the median daily AQI was 22. That median is lower than the typical monitored county in Missouri (median 38.5 across 20 counties), and lower than the typical monitored U.S. county (39). The main pollutant was fine particles (PM2.5) on 122 days. Across the years with fuller monitoring, the share of Good days fell: an average of 100% in 1993–1995 versus 92% in 2017–2020.

EPA did not report an AQI for every day of 2020 here (122 of 366 days). Figures describe monitored days only; seasonal monitoring (for example, ozone measured only in warmer months) can make a county look cleaner or dirtier than a full-year record would.

Years with fewer than 120 monitored days (2018, 2021, 2022, 2023, 2024, 2025…) are shown in the table but left out of comparisons and trend statements.

How the days broke down each year

Each bar is one year. The colored segments show the share of monitored days that fell in each AQI category.

Typical and high-end AQI over time

The median is the middle day of the year. The 90th percentile is the level that only the highest 10% of days exceeded.

Main pollutant by day, 2020

On each monitored day, the AQI reflects whichever measured pollutant had the highest index. This counts how many days each pollutant set the AQI. A pollutant that was not measured here cannot appear.

What this data can and can’t tell you

It is a county-level summary. EPA reports one AQI per day for the county, based on the monitors operating there. Air at a particular street, school or home can differ, especially near roads, industry or wildfire smoke.

It is not a health assessment. The AQI is EPA’s scale for communicating daily air quality. A county’s history can’t tell you what the health risk is for any particular person. For daily conditions and health guidance, see AirNow.

Rules change over time. EPA has revised AQI breakpoints, most recently for fine particles in 2024, so some year-to-year change can reflect the scale rather than the air.
