Air quality today
The air quality in Ayabe is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 15.0 µg/m³, based on four valid observations reported through OpenAQ. This reflects the latest available data for the city. 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 dataset for Ayabe contains measurements of four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All readings come from a single monitoring site located at 綾部市宮代町土代３６, so the city’s air‑quality picture is based on one station that contributed four rows of data.
Each pollutant shows a single recorded value because the minimum, median and maximum are identical across the dataset. NO was measured at 0.002 ppm, NO₂ at 0.007 ppm, NOX at 0.009 ppm and PM2.5 at 15.0 µg/m³. The spread for each is effectively zero – the 10th and 90th percentiles match the single value recorded, indicating no observed variation within the sampled period.
All four measurements were last updated on 2026‑02‑10 22:00 UTC, which falls within three days of today’s date (2026‑02‑13). This means the data are relatively fresh, but because they all originate from the same timestamp and location, they provide only a snapshot rather than a continuous or city‑wide view. Consequently, while the numbers give an immediate sense of current concentrations at that specific site, they do not capture spatial differences across Ayabe or any short‑term fluctuations that might occur elsewhere in the city.
