Air quality today
The air quality in Chesterfield County, Virginia is currently classified as Moderate. The primary pollutant identified is PM2.5, with a reference concentration of 12.0 µg/m³; the reference value for PM10 is 23.0 µg/m³. The PM2.5 reference value of 12.0 µg/m³ represents the level used for comparison in the assessment. The PM10 reference value of 23.0 µg/m³ provides a secondary benchmark. A total of five valid observations contributed to the current rating. The latest data timestamp is 2026-02-23 12:00 UTC. The moderate classification reflects the combined analysis of the five recent PM2.5 observations. No other pollutant exceeds its reference threshold in the current dataset.

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 data for Chesterfield County, Virginia currently contains three measured pollutants—ozone (O3), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). Each pollutant is represented by a single monitoring record, so the dataset comprises three rows in total. All three observations come from the same sensor location on Beach Road. The ozone reading is 0.031 ppm, the PM10 concentration is 23.0 µg/m³ and the PM2.5 concentration is 11.5 µg/m³. For each pollutant the minimum, median and maximum values are identical, indicating that only one measurement point is available for each and no range of values is captured within the dataset.
The timestamps show that the information is fairly fresh: the ozone measurement was last updated on 2026-01-29 14:00 UTC, while the PM10 and PM2.5 values were refreshed on 2026-02-10 23:00 UTC. All three records fall within the last 30 days, which is the only time window with data for this city. Because the dataset relies on a single monitoring site, it does not capture spatial variability across Chesterfield County, and the lack of multiple rows means that temporal trends or day‑to‑day fluctuations cannot be assessed from these numbers alone. Users should keep in mind that air quality can differ by neighborhood and time of day, and the current snapshot reflects conditions at one location on the dates shown.
