Air quality today
The air quality in Kitajima 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 five valid observations reported through OpenAQ. 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 Kitajima air‑quality record draws on a single monitoring location (板野郡北島町鯛浜字向４３－４). All five pollutants tracked by OpenAQ – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂) – are represented in the dataset. The most recent readings for each pollutant were logged on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window.
Across the five measured species the data show very narrow statistical spreads because only one observation is available per pollutant. NO and SO₂ both register a constant value of 0.0 ppm, with minimum, median and maximum all equal to zero. NO₂ and NOX each have a single reported concentration of 0.011 ppm, again identical at the 10th and 90th percentiles. PM2.5 is recorded at 13.0 µg/m³, with no variation in the limited sample. Because there is only one monitoring row, typical or median values are effectively the same as the extremes, and no intra‑city variability can be inferred from this dataset.
The coverage therefore remains modest: a single sensor supplies all pollutant readings for Kitajima, and while the timestamps are recent, the lack of multiple stations means that spatial differences in air quality across the town cannot be captured. Users should keep in mind that conditions may differ elsewhere in the city or change after the last update, as the current snapshot reflects only one point in time and place.

Data notes
The data shown for Kitajima is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T22:00:00+00:00, meaning it has been updated within three days. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
