Air quality today

The air quality in Fort St. John is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).

Measurements from six valid monitoring points show a PM2.5 reference value of 2.5 µg/m³ and a PM10 reference value of 25.0 µg/m³. These values are derived from data shown via OpenAQ.

What the data includes

Fort St. John’s air‑quality feed draws from a single monitoring location that reports six key pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All of the latest measurements were recorded at 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” freshness window, so the data reflect conditions from only a few days ago.

Because there is just one row of data for each pollutant, the reported values are identical across statistical summaries – the minimum, median and 90th‑percentile all match the single measurement. NO sits at 0.0036 ppm, NO₂ at 0.0026 ppm, O₃ at 0.034 ppm, PM₁₀ at 25.0 µg/m³, PM₂.₅ at 2.5 µg/m³ and SO₂ at 0.0007 ppm. This uniformity means there is no observed spread or variability within the dataset for Fort St. John; each pollutant’s range collapses to a single point.

The limited station coverage implies that the snapshot represents conditions only at the “FORT ST JOHN LEARNIN” site and may not capture spatial differences across the broader city area. While the timestamps are recent, the absence of multiple monitoring points or historical depth restricts insight into how concentrations change over time or between neighborhoods. Users should keep in mind that air‑quality can vary locally, and the present figures provide a concise but narrowly scoped view of Fort St. John’s current atmospheric composition.

Data notes

The current dataset for Fort St. John includes six valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is labeled as updated within three days. This snapshot reflects conditions at the time of collection, but air quality can vary across different neighborhoods and times of day within the city, so values may not represent every location or moment.
