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 Kanuma includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All of these come from a single monitoring location at 鹿沼市今宮町１６８８－１, so the city‑wide coverage is limited to one station row per pollutant. The most recent reading for each compound was recorded on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness category, indicating that the data are currently up‑to‑date.
Because there is only one observation point, the statistical spread for each pollutant is effectively zero. The minimum, median and maximum values are identical: NO registers at 0.001 ppm, NO₂ at 0.003 ppm, NOX at 0.004 ppm and PM2.5 at 8.0 µg/m³. Consequently, the inter‑percentile range (10th to 90th percentile) is also a single value for every metric. This uniformity reflects the limited spatial sampling rather than a stable atmospheric condition across Kanuma.
With just one active sensor, the dataset cannot capture variations that might exist in different neighborhoods or at other times of day. While the timestamps are recent, the lack of multiple stations means any city‑wide assessment must be treated cautiously; conditions could differ elsewhere in Kanuma. Users should keep in mind that the available figures represent a snapshot from a single site rather than a comprehensive picture of air quality throughout the municipality.

Data notes
The current data for Kanuma are based on four valid measurements and were updated within three days, with the latest refresh recorded at 2026‑02‑10 22:00 UTC. This snapshot reflects conditions at a single point in time; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
