Air quality today
The air quality in the City of Cold Lake is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 10.9 µg/m³ based on two valid observations reported through OpenAQ.
These measurements indicate that fine particulate matter is the dominant factor influencing today’s air quality assessment. 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 City of Cold Lake air‑quality feed includes data for two pollutants, ozone (O₃) and fine particulate matter (PM₂.5). All observations come from a single monitoring location – Cold Lake South – and the dataset contains two rows in total, one for each pollutant. The most recent measurements were recorded on 2026‑02‑10 at 22:00 UTC, and both are flagged as having been updated within the past three days, so the information is relatively fresh.
For ozone, the only reported value is 0.025 ppm, which is also the minimum, median and maximum across the dataset; there is no observed spread beyond this single figure. The same pattern holds for PM₂.5, where the concentration is consistently recorded as 10.9 µg/m³ in every row, again representing the full range of values captured. Because each pollutant has just one data point, typical (median) and extreme (minimum/maximum) readings are identical.
The coverage is limited to a single site, meaning that spatial variations across Cold Lake are not reflected in these numbers. While the timestamps are current, the lack of multiple stations or repeated measurements means the dataset cannot describe how air quality might differ elsewhere in the city or change over time. Users should keep in mind that conditions can vary by location and moment, even though the available data for O₃ and PM₂.5 are up‑to‑date for the reporting point.

Data notes
The data shown reflects two 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 brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
