Air quality today

The air quality today in Prince George is classified as Good. The primary pollutant identified for the current assessment is PM2.5 (fine particles).

Measurements show a PM2.5 reference value of 1.7 µg/m³ and a PM10 reference value of 16.0 µg/m³, based on eleven valid observations collected through OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Prince George pulls from two monitoring sites and contains eleven recent observations across eight measured pollutants. Available measurements are nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter of three size fractions (PM1, PM2.5, PM10) and sulfur dioxide (SO2), together with relative humidity. All values were recorded at the same moment – 2026‑02‑10 22:00 UTC – so the data are uniformly fresh, with no older or unknown timestamps.

Across the two stations the reported numbers show very little variation. For PM2.5 the median value is 0.85 µg/m³, ranging from a minimum of 0.0 to a maximum of 1.7 µg/m³; the 10th and 90th percentiles are 0.17 and 1.53 respectively, indicating that most recent readings cluster near the low end of the observed spread. The other gases each have a single recorded value: NO is consistently 0.0012 ppm, NO2 0.0023 ppm, O3 0.03 ppm and SO2 0.0001 ppm at the PRG Plaza 400 site. PM10 is reported as a constant 16.0 µg/m³, while PM1 registers 0.0 µg/m³ at Vista Ridge Dr. Relative humidity is measured at 32.31 % at the same Vista Ridge location.

Because each pollutant is represented by only one or two recent rows, the dataset provides a snapshot rather than a detailed time series. The uniform timestamp means conditions can differ across neighbourhoods and times of day that are not captured here, so while the numbers give an up‑to‑date picture for the moment they were taken, they do not reflect longer‑term variability in Prince George’s air quality.

Data notes

The data shown reflects 11 valid measurements and is Updated within 3 days, with the most recent update recorded at 2026‑02‑10T22:00:00+00:00. These values provide a snapshot of ambient conditions across Prince George, but air quality can differ by specific neighbourhoods, micro‑environments and time of day, so local variations may not be captured in this summary.
