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 New Westminster air‑quality dataset contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). All four are represented by a single reporting row each, giving the city a total of four data rows in the current snapshot. Each pollutant’s most recent observation was recorded on 2026‑02‑10 at 22:00 UTC, and every entry is flagged as having been updated within the past three days, indicating that the available values are relatively fresh.
Across the pollutants the reported concentrations show no variability within each series: NO is consistently 0.002 ppm, NO₂ stays at 0.006 ppm, O₃ remains at 0.027 ppm and PM₂.5 holds steady at 2.6 µg/m³. The minimum, median, maximum, as well as the 10th and 90th percentiles are identical for each compound, meaning that the dataset captures a single point in time rather than a range of measurements. Because only one row per pollutant is present, there is no spread to describe trends or fluctuations over the recent period.
The limited number of rows means coverage is narrow; while the data are up‑to‑date, they represent just one location and moment for each pollutant. Consequently, conditions in other parts of New Westminster or at different times may differ from what these figures show. Users should keep in mind that the snapshot provides a concise view of current levels but does not reflect broader spatial or temporal variation within the city.
