Air quality today
The air quality today in Airdrie, Alberta is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements recorded by OpenAQ show a PM2.5 concentration of 1.4 µg/m³ based on four valid observations. No PM10 value is reported for this period. The observed concentration aligns with the reference level used for assessment. Four separate sensors contributed data, each meeting quality criteria. All values are presented in micrograms per cubic metre. Data is shown via OpenAQ, which aggregates information from monitoring stations across the region. These readings reflect conditions at the time of collection and are not averaged over longer periods. 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 Airdrie air‑quality feed contains data for five pollutants measured at a single monitoring location. Carbon monoxide, nitrogen oxide, nitrogen dioxide, ozone and fine particulate matter (PM2.5) are all represented, giving a basic snapshot of the city’s ambient composition. The dataset includes five rows in total, each row corresponding to one pollutant reading from that station.
The most recent values are fairly current for four of the pollutants, with updates recorded on 2026‑02‑10 at 22:00 UTC. At that time carbon monoxide was reported at 0.3 ppm, nitrogen oxide at 0.0 ppm, nitrogen dioxide at 0.002 ppm, ozone at 0.041 ppm and PM2.5 at 1.4 µg/m³. Carbon monoxide is the only measurement whose latest timestamp is older, dated 2025‑10‑02 at 15:00 UTC, so its freshness lags behind the others by several months. All five pollutants show a single recorded value with no variation across the dataset; each has identical minimum, median and maximum figures, indicating that only one observation per pollutant is currently stored.
Because the data set consists of just one monitoring site, it does not capture spatial differences that may exist across Airdrie. The uniformity of the numbers also means there is no observable spread or range for any pollutant, limiting insight into short‑term fluctuations. While the recent timestamps suggest the feed is being updated regularly for most pollutants, the older carbon monoxide entry highlights a gap in coverage that could affect how fully current conditions are reflected. Users should keep in mind that air quality can change throughout the day and across neighborhoods, and this single‑point snapshot provides only a limited view of overall city conditions.

Data notes
The data shown for Airdrie reflects four valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of ambient conditions but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
