Air quality today
The air quality in Mihama is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 10.0 µg/m³ based on four valid observations reported through OpenAQ.
These measurements reflect the present conditions without implying any trend or cause. 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
Mihama’s OpenAQ feed contains four pollutant measurements collected from a single monitoring site located at 知多郡美浜町大字奥田字儀路６７－１. The dataset includes nitrogen monoxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). Each pollutant has only one recorded value because the station provides a single row per compound, so the overall coverage consists of four rows representing the four substances.
All observations are recent: the most recent timestamp for every pollutant is 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness window. The NO reading is consistently zero across its minimum, median and maximum (0.0 ppm), indicating no detectable variation at this site during the reporting period. By contrast, NO2 and NOX share identical statistics – a single value of 0.012 ppm that serves as the minimum, median, 10th percentile, 90th percentile and maximum for each, showing an exact but very low concentration with no spread. PM2.5 is reported at 10.0 µg/m³ uniformly across all statistical markers, again reflecting a single‑point measurement without observed fluctuation.
Because the data come from only one location, spatial representation of Mihama’s air quality is limited; conditions elsewhere in the town may differ from those captured here. Nonetheless, the dataset is fully up‑to‑date, and each pollutant’s range is effectively a point value rather than a distribution, which means there is no internal variability to describe for this particular monitoring site.

Data notes
The data shown reflects four valid measurements and was refreshed within the past three days, with the most recent update recorded at 2026‑02‑10 22:00 UTC. This snapshot provides a brief view of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
