Air quality today

The air quality in Kurashiki is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 23.0 µg/m³. Data are based on 44 valid observations collected through OpenAQ.

These measurements reflect the present conditions without reference to trends or forecasts. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Kurashiki pulls hourly readings from nine monitoring sites and contains a total of forty‑four individual rows. All six pollutants tracked by OpenAQ—carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂)—are represented, but the number of stations contributing to each varies. CO is reported from only two sites, NO, NO₂ and NOX each come from nine locations, PM2.5 also has nine contributors, while SO₂ is measured at six stations.

The most recent observations for every pollutant were recorded on 2026‑02‑10 at 22:00 UTC, so the data are uniformly fresh across the board. Median values give a quick sense of typical conditions: CO sits around 0.35 ppm, NO at 0.001 ppm, NO₂ at 0.01 ppm, NOX at 0.011 ppm, PM2.5 at 19 µg/m³ and SO₂ at 0.001 ppm. The spreads are modest but noticeable; for example, CO ranges from 0.3 to 0.4 ppm, while PM2.5 varies between 17 and 23 µg/m³. Percentile checks show that the lower‑10 % of NO readings are at the detection limit (0.001 ppm) and the upper‑90 % remain below 0.006 ppm, indicating a fairly tight distribution for nitrogen monoxide.

Because some pollutants rely on fewer stations—particularly CO with only two reporting sites—the city‑wide picture may miss localized spikes that other monitors would capture. Overall, the dataset offers recent, multi‑pollutant coverage but reflects uneven spatial density across the different gases and particles.
