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 Christchurch includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). All values come from a single monitoring location, the Christchurch – St Albans EP station, so the city‑wide coverage is limited to one row of data for each pollutant.
Each pollutant has a single recent reading that was last updated on 2026-02-10 21:00 UTC. The NO concentration is recorded at 0.5628 µg/m³, NO₂ at 1.5955833 µg/m³, PM₁₀ at 8.9282217 µg/m³ and PM₂.5 at 3.3712976 µg/m³. Because there is only one observation per pollutant, the minimum, median, maximum, 10th percentile and 90th percentile values are all identical, indicating no observed spread in the data set.
With just one active station, the dataset does not capture spatial variation across Christchurch, and the lack of multiple rows means that any temporal trends or day‑to‑day fluctuations cannot be assessed from this source alone. While the timestamps are current – all measurements were recorded within the last week – the single‑point nature of the data limits its ability to represent broader city conditions, which can differ by neighbourhood and time of day.
