Air quality today

The air quality in Kure is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 13.0 µg/m³ based on ten valid observations reported through OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Kure air‑quality record draws on data from two monitoring sites, each reporting within the last three days (most recent reading timestamp 2026‑02‑10 22:00 UTC). All five key pollutants—nitric oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂)—are represented in the dataset.

Across the two stations, NO values are consistently low, ranging from 0.0 to 0.001 ppm with a median of 0.0005 ppm. NO₂ shows a slightly higher but still narrow band, spanning 0.01‑0.013 ppm and centering on a median of 0.0115 ppm; the combined NOX metric mirrors this pattern (0.011‑0.013 ppm, median 0.012 ppm). PM2.5 is reported as a single value of 13.0 µg/m³ at both sites, indicating no observed variation in the current sample. SO₂ registers uniformly at 0.0 ppm.

These figures illustrate that the available measurements are very recent and tightly clustered, suggesting limited short‑term fluctuation within the sampled locations. However, with only two reporting stations, spatial coverage across Kure is modest, meaning conditions may differ in neighborhoods not directly monitored. The dataset’s freshness (all timestamps within three days) provides a current snapshot, but the narrow station count and uniform values for some pollutants highlight that broader city‑wide trends cannot be inferred from this limited sample alone.

Data notes

The data shown for Kure is based on ten valid measurements and was refreshed recently, having been updated within three days (last update 2026‑02‑10T22:00:00+00:00). These readings represent a snapshot of ambient conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not reflect current or localized conditions elsewhere in the city.
