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 Madawaska Parish draws from a single monitoring site on Edmundston Queen Street, giving three rows of data—one each for nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). All three measurements were last refreshed on 2026-02-10 23:00 UTC, which falls within the “updated within 3 days” freshness window, so the dataset reflects very recent conditions.
For NO2 the sensor reports a constant value of 0.0251 ppm; both the minimum and maximum observed values are identical, and the median matches this figure as well. Ozone shows the same pattern, with a single reported concentration of 0.019 ppm across its entire record. PM2.5 is measured in micrograms per cubic metre and records a uniform value of 15.0 µg/m³, again with no variation between minimum, median or maximum.
Because only one station contributes data, the coverage for Madawaska Parish is limited to this specific street location; there are no additional rows that capture spatial differences across the wider area. The lack of variability in each pollutant’s statistics indicates that the dataset consists of a single recent snapshot rather than a range of observations over time. Consequently, while the figures give an up‑to‑date picture for the exact spot on Edmundston Queen Street, they do not convey how air quality might differ elsewhere in the parish or across longer periods.
