Air quality today
The air quality in Coldstream today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements from five monitoring points show a PM2.5 concentration of 2.42 µg/m³, based on the most recent data available through OpenAQ. This reflects the current level of fine particulate matter in the city’s atmosphere.

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
Coldstream’s air‑quality feed draws from a single monitoring row that records six variables: PM1 at 1.60 µg/m³, PM10 at 2.0 µg/m³, PM2.5 at 2.42 µg/m³, relative humidity at 42.21 %, temperature at 10.92 °C and particle concentration (UM003) at 565.19 particles/cm³. All six measurements are supplied by OpenAQ; the most recent data for five of them were logged on 2026‑02‑10 22:00 UTC, while the PM10 reading is older, last updated on 2024‑10‑03 17:00 UTC.
The dataset shows a very narrow statistical spread – each pollutant’s minimum, median and maximum values are identical, indicating that only one observation per variable is currently available. Consequently, there is no range to describe variability over time; the single recorded value serves as both the typical and extreme measurement for the city at the moment of capture.
Because the station count is limited to one row, coverage across Coldstream is minimal. The freshness of most parameters (within three days) suggests recent conditions are reflected for temperature, humidity, PM1, PM2.5 and UM003, but the older PM10 value highlights an uneven update schedule. Users should keep in mind that air‑quality can differ across neighborhoods and over longer periods, and the present snapshot may not capture those spatial or temporal variations.
