Air quality today
The air quality in Imari is currently classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 6.0 µg/m³ based on five valid observations reported through OpenAQ.
These values indicate that the fine‑particle level is within the reference range for this category. 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 Imari air‑quality dataset currently contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these values come from a single monitoring location at 伊万里市大坪町２８６３－１, so the city’s coverage is limited to one station but five distinct data rows, each representing a different pollutant.
The most recent readings were all recorded on 2026‑02‑10 at 22:00 UTC and are flagged as “Updated within 3 days,” indicating that the data are fresh for each parameter. For NO the reported value is exactly 0.0 ppm, while both NO₂ and NOX show a uniform concentration of 0.006 ppm across their minimum, median and maximum statistics. PM2.5 is consistently measured at 6.0 µg/m³, again with no variation between its 10th‑percentile, median and 90th‑percentile values. SO₂ mirrors NO with a steady reading of 0.0 ppm. Because each pollutant’s statistical spread (min, median, max, p10, p90) is identical, the dataset does not reveal any intra‑day variability at this site.
With only one monitoring point, the data give a snapshot rather than a citywide picture; conditions can differ in other neighborhoods or at different times of day. Nevertheless, the current record provides a clear and up‑to‑date baseline for each listed pollutant as of the last update.
