What the data includes

The dataset for Kazo includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX) and fine particulate matter (PM2.5). All observations come from two monitoring stations, providing a total of eight recent rows that were last refreshed on 2026‑02‑10 at 22:00 UTC. Because every row is marked as “Updated within 3 days,” the information reflects conditions that are only a few days old.

Across the two sites the recorded concentrations show modest variability. NO values range from 0.001 ppm to 0.005 ppm, with a median of 0.003 ppm and the central 80 % falling between roughly 0.0014 ppm and 0.0046 ppm. NO₂ measurements are slightly higher, spanning 0.015‑0.023 ppm; the median sits at 0.019 ppm and the 10th–90th percentile band is narrow, from about 0.0158 ppm to 0.0222 ppm. The combined NOX metric mirrors this pattern, ranging from 0.016‑0.028 ppm, a median of 0.022 ppm and an inter‑percentile spread of roughly 0.0172‑0.0268 ppm. PM2.5 concentrations are reported in micrograms per cubic metre, varying between 11.0 µg/m³ and 16.0 µg/m³; the median is 13.5 µg/m³ and the central 80 % lie between 11.5 µg/m³ and 15.5 µg/m³.

The data set therefore offers a concise, recent snapshot of air quality in Kazo, but its coverage is limited to just two locations. While the timestamps are fresh, the small number of stations means that conditions can differ across neighborhoods or at times not captured by these measurements. Users should keep in mind that this view reflects only the specific sites and the narrow time window represented by the latest updates.

Data notes

The data shown for Kazo reflects eight valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. While this snapshot provides a current overview of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
