Air quality today

The air quality in Sherwood Park today is rated as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 6.9 µg/m³, based on 19 valid observations reported through OpenAQ. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Sherwood Park’s OpenAQ feed currently draws from five monitoring stations and a total of twenty‑six recent rows of data. The dataset includes measurements for carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM₁, PM₂·₅, PM₁₀), relative humidity, sulfur dioxide (SO₂), temperature and particle count (UM003). Most of the values were recorded on 2026‑02‑10 at 22:00 UTC, which the system flags as “updated within three days”, giving a snapshot that is essentially real‑time for those pollutants. The exception is PM₁₀, whose latest entry dates back to 2025‑01‑13 at 23:00 UTC and is therefore classified as old data.

Across the recent records, the particulate matter shows a modest spread. PM₂·₅ values range from about 0.13 µg/m³ up to 11.23 µg/m³ with a median of 4.2 µg/m³; PM₁ varies between 0 and 7.69 µg/m³, centering around a median of 2.72 µg/m³. The particle count (UM003) spans from roughly 147 to 1 073 particles per cubic centimetre, with a typical value near 597. Temperature readings are clustered between –7.85 °C and 10.73 °C, the middle of which sits at about 10.40 °C on the day of measurement. Relative humidity is fairly narrow, ranging from 32.0 % to 46.4 %, with a median of 32.68 %. For gases, NO₂ values sit between 0.009 and 0.017 ppm (median 0.013 ppm) and O₃ between 0.025 and 0.033 ppm (median 0.029 ppm).

The coverage is uneven: while most pollutants have fresh data from the same recent timestamp, PM₁₀ relies on a much older record, and some rows are marked “unknown” or lack recent updates. Consequently, the snapshot reflects current conditions for many key metrics but may miss recent changes in coarse particulate levels. Users should keep in mind that air quality can differ across neighbourhoods and over short periods, especially when parts of the dataset are not up to date.
