Air quality today
The air quality in Inuyama is currently classified as Moderate, with PM2.5 identified as the primary pollutant.
Measurements from five valid observations show a PM2.5 concentration of 10.0 µg/m³. This data is shown via OpenAQ. 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
The Inuyama air‑quality dataset currently contains measurements from a single monitoring site located at 犬山市大字五郎丸字下前田１. Five pollutants are reported: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All five variables have one recorded value each, so the dataset consists of five rows in total.
Each pollutant shows an identical timestamp for its most recent observation: 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” freshness window. Because there is only one station, the reported statistics are all identical – the minimum, median and maximum values are the same for every pollutant. NO registers at 0.001 ppm, NO₂ at 0.011 ppm, NOX at 0.012 ppm, PM2.5 at 10.0 µg/m³ and SO₂ at 0.002 ppm. Consequently there is no observed spread or variability across the data; each pollutant’s 10th‑percentile and 90th‑percentile values match the single measurement.
The limited spatial coverage means that these figures represent conditions only at the specific address in Inuyama, not the broader city environment. While the timestamps are recent, the dataset does not provide multiple observations over time or across different neighborhoods, so any change in air quality throughout the day or week cannot be assessed from this snapshot. Users should keep in mind that actual conditions elsewhere in Inuyama may differ from those recorded at this lone location.
