Air quality today
The air quality in Kan‑onji today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 28.0 µg/m³ based on five valid observations.
These measurements indicate that particulate matter levels are present but not extreme, and no additional pollutants have been highlighted for today. 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 data for Kan‑onji includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), the combined nitrogen oxides metric (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these are reported from a single monitoring site located at 観音寺市坂本町１－１－１, giving a total of five data rows, one for each pollutant.
Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, which is within the last three days and therefore reflects current conditions. The values are very consistent across the limited dataset: NO, NOX and SO₂ all read exactly 0.0 ppm, while NO₂ registers 0.008 ppm. PM2.5 shows a concentration of 28.0 µg/m³. For every pollutant the minimum, median and maximum values are identical, indicating that only a single measurement is available for each metric at this time.
Because the dataset comes from just one station, it captures conditions only at that specific address and does not represent spatial variation across the wider city area. The uniform timestamps mean there are no older or unknown‑age entries, but the lack of multiple locations limits the ability to describe broader air‑quality patterns in Kan‑onji. Nonetheless, the available figures give a clear snapshot of the current levels for each of the five pollutants at the monitored site.
