Air quality today

The air quality in Aylesford Mountain is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 1.5 µg/m³ based on two valid observations reported through OpenAQ. No PM10 data are available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Aylesford Mountain pulls information from a single monitoring site that reports three separate air‑quality variables: nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). In total there are three rows of data – one row per pollutant – all originating from the same station in the community.

The NO2 record is dated 2017‑04‑24 17:00 UTC, which makes it considerably older than the other measurements and classifies it as “old” data. By contrast, both O3 and PM2.5 were last refreshed on 2026‑02‑10 22:00 UTC, meaning they have been updated within the past three days and are therefore current. The ozone reading is a constant 0.037 ppm across its minimum, median and maximum values, while the fine‑particle measurement sits at a steady 1.5 µg/m³ for all statistical points. NO2 shows a uniform value of 0.0 ppm throughout its record.

Because only one monitoring location contributes to the dataset, spatial coverage is limited; variations in air quality across different parts of Aylesford Mountain cannot be captured by these figures alone. The timestamps illustrate an uneven freshness profile: recent data are available for O3 and PM2.5, but the nitrogen‑dioxide figure remains over six years old. Consequently, any snapshot drawn from this set reflects a narrow view in both time and place, with the most reliable insight coming from the up‑to‑date ozone and particulate readings while the NO2 value should be treated as historical rather than representative of current conditions.

Data notes

The data shown reflects two valid measurements and is updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 22:00 UTC. While this snapshot provides a current view of air quality in Aylesford Mountain, conditions can differ across neighbourhoods and change throughout the day, so local variations may exist beyond what is captured here.
