Air quality today
The air quality in Redwater today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements from four valid observations show a PM2.5 concentration of 4.5 µg/m³, which aligns with the reference value provided for this pollutant.
Data are displayed via OpenAQ and reflect the current assessment for the city. 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
Redwater’s air‑quality feed includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). The dataset is built from a single monitoring station that contributed four rows of data, one for each pollutant. All observations were recorded at the same moment, 2026‑02‑09 23:00 UTC, which falls within the “updated within three days” window and therefore represents a very recent snapshot of conditions in the city.
The values reported are uniform across the dataset because each pollutant has only one measurement point. NO is measured at 0.004 ppm, NO₂ at 0.009 ppm, O₃ at 0.034 ppm and PM₂.5 at 4.5 µg/m³. For every pollutant the minimum, median, maximum, 10th percentile and 90th percentile are identical to the single recorded value, indicating no observed spread or variability in this particular sample. Because there is only one station, the coverage does not capture spatial differences that might exist across Redwater; conditions can differ in other neighbourhoods or at other times of day.
Overall the data set is fresh and complete for the listed pollutants, but its breadth is limited to a single location and a single timestamp. Consequently, while the numbers give an accurate picture of air quality at that specific point in time, they do not reflect temporal trends or city‑wide variation. Users should keep in mind that additional monitoring sites would be needed to describe how pollutant levels change across Redwater throughout the day or week.
