Air quality today
The air quality in Cranbrook today is classified as Good. The primary pollutant measured is PM2.5 (fine particles).
Four valid measurements were recorded, showing a PM2.5 reference value of 0.9 µg/m³. No PM10 data are available for this 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 air‑quality record for Cranbrook draws on a single monitoring site – the Muriel Bax station – which supplies four pollutant measurements. The dataset therefore consists of one row per pollutant, giving a total of four observations across the city. All four values were last refreshed on 2026‑02‑10 at 22:00 UTC, so the information is current within the past three days for each contaminant.
The available pollutants are nitrogen monoxide (NO) at 0.0001 ppm, nitrogen dioxide (NO₂) at 0.0008 ppm, ozone (O₃) at 0.039 ppm and fine particulate matter (PM2.5) at 0.9 µg/m³. For each of these, the minimum, median and maximum recorded values are identical, indicating that only a single measurement exists for the reporting period. Consequently there is no observed spread or variability in the data; the reported figure represents both the typical and extreme reading for the latest update.
Because the dataset contains just one station, spatial coverage across Cranbrook is limited to the location of the Muriel Bax monitor. While the timestamps are recent, the lack of multiple sites means that conditions elsewhere in the city may differ from what is captured here. Users should keep in mind that these four figures provide a snapshot rather than a comprehensive picture of air quality throughout the entire community.
