Air quality today
The air quality in St. Albert today is classified as Good. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 3.0 µg/m³ based on four valid observations from OpenAQ data.
Overall conditions meet the Good category criteria, and the measurement set includes four valid readings for PM2.5 at 3.0 µg/m³. 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 St. Albert contains five measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM2.5) – drawn from a single monitoring station, giving one row of data per pollutant. The most recent observation across all pollutants is from 2026‑02‑10 22:00 UTC, so the newest timestamps are within three days of today, indicating fairly fresh coverage for most compounds. CO is the only pollutant whose last update is older, recorded on 2026‑01‑21 14:00 UTC, which means its value has not been refreshed for about three weeks.
All five pollutants show a single reported value with no variation in the recent record set: CO registers at 0.0 ppm, NO at 0.003 ppm, NO₂ at 0.013 ppm, O₃ at 0.038 ppm and PM2.5 at 3.0 µg/m³. Because each pollutant has only one measurement point, the minimum, median, maximum, 10th percentile and 90th percentile are identical, so there is no observable spread or range in the data for any of them.
The coverage is limited to just one station, which means spatial variation across St. Albert cannot be captured; conditions may differ in other neighbourhoods or at different times of day. While the timestamps for NO, NO₂, O₃ and PM2.5 are recent, the older CO reading highlights an uneven update frequency among the pollutants. Users should keep in mind that this snapshot reflects a single location and moment rather than a comprehensive city‑wide picture.
