Air quality today
The air quality in Colerain Township, Ohio is rated as Moderate today. The primary pollutant identified is PM2.5 (fine particles).
Measurements from OpenAQ show a PM2.5 concentration of 16.9 µg/m³ based on two valid readings. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Colerain Township includes three pollutant measurements drawn from a single monitoring location that supplies data on ozone (O3), fine particulate matter (PM2.5) and sulfur dioxide (SO2). In total there are three rows of observations, all tied to the same station in the township.
The most recent reading for O3 is 0.001 ppm recorded at Colerain on 2025-11-01 05:00 UTC, while both PM2.5 and SO2 have their latest values from 2026-02-10 23:00 UTC—16.9 µg/m³ for PM2.5 and 0.002 ppm for SO2. Two of the three rows were updated within the past seven days, and one row dates back to late 2025, indicating that most of the data is fairly fresh but a portion is older.
All three pollutants show identical minimum, median and maximum values (O3 = 0.001 ppm, PM2.5 = 16.9 µg/m³, SO2 = 0.002 ppm), so there is no observed variability within the current sample set. Because only one monitoring site contributes data, the coverage across the township is limited; conditions can differ in other neighborhoods or at different times of day that are not captured here.
Overall, the dataset provides a snapshot of three key air‑quality constituents with recent timestamps for two pollutants and a slightly older reading for ozone, but it lacks broader spatial representation and does not show any range of values beyond the single reported figures.
