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 dataset for Regina includes four measured pollutants – nitrogen dioxide (NO2), ozone (O3), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All values come from a single monitoring location, so the city’s air‑quality picture is based on one station that reports each pollutant in its own row.
For three of the pollutants – NO2, O3 and PM2.5 – the most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, meaning the data are fresh within the last three days. The reported concentrations are identical across their statistical summaries: NO2 is consistently 0.005 ppm, O3 stays at 0.023 ppm and PM2.5 remains at 3.0 µg/m³, with no variation between minimum, median or maximum values. In contrast, the PM10 measurement is much older; its last update dates back to 2016‑08‑21 at 14:00 UTC, also showing a single unchanging value of 3.0 µg/m³.
Because each pollutant has only one recorded figure, there is no spread or range to describe – the minimum, median and 90th‑percentile values are all identical for every metric. This uniformity indicates that the current dataset does not capture temporal fluctuations or spatial differences within Regina. Users should keep in mind that conditions can differ across neighborhoods and over time, especially given that PM10 data are a decade old while the other three pollutants are only recently refreshed.
