Air quality today
The air quality in Moncton today is classified as Good. The primary pollutant identified for the current assessment is PM2.5 (fine particles).
Measurements recorded from three valid monitoring stations show a PM2.5 concentration of 7.3 µg/m³. No PM10 value is available for this period. 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 Moncton air‑quality dataset currently contains a single monitoring row, so each pollutant is represented by one observation from the same station in the city. The three measured pollutants are nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). All values were recorded at the same moment – 2026‑02‑10 22:00 UTC – which means the data are fresh, having been updated within the last three days for every pollutant.
For NO2 the concentration is 0.0069 ppm; this is both the minimum and maximum reported value, so there is no observed spread and the median equals the single measurement. O3 shows a uniform reading of 0.034 ppm, again with identical min, max and median values. PM2.5 is reported as 7.3 µg/m³, likewise without any variation across the dataset. Because each pollutant has only one data point, statistical summaries such as percentiles or inter‑quartile ranges are not applicable beyond the single recorded figure.
The limited coverage – just one row for the whole city – means that spatial differences in air quality cannot be captured here. While the timestamps are recent, the lack of multiple stations or repeated measurements restricts insight into how conditions might change across neighbourhoods or over time. Users should keep in mind that these figures represent a snapshot from a single location on 2026‑02‑10 and may not reflect broader city‑wide variations.

Data notes
The current air‑quality values for Moncton are based on three valid measurements and were updated within 3 days (last refresh: 2026‑02‑10T22:00:00+00:00). These figures represent a snapshot in time; conditions can differ across neighbourhoods and may change throughout the day, so local variations are possible.
