Air quality today

The air quality in Kagoshima is currently rated as Good. The primary pollutant identified is PM2.5, with a measured concentration of 8.0 µg/m³ based on 21 valid observations reported through OpenAQ.

These measurements indicate that fine particulate levels are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Kagoshima air‑quality feed includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM₂.5) and sulfur dioxide (SO₂). Data come from 21 individual rows collected at four monitoring stations across the city, giving a modest but spatially varied picture of ambient conditions.

All pollutant readings are recent, with the newest timestamps recorded on 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” window. CO is reported from a single station (鹿児島市鴨池二丁目31番15号) at a constant value of 0.3 ppm. The other five gases are measured at four stations (鹿児島市喜入町６２２７), each showing low concentrations: NO ranges from 0.0 to 0.002 ppm with a median of 0.0005 ppm; NO₂ varies between 0.001 and 0.006 ppm, median 0.003 ppm; NOX spans 0.002–0.008 ppm, median 0.003 ppm; SO₂ is consistently low at 0.0–0.001 ppm, median 0.001 ppm. PM₂.5 values are expressed in micrograms per cubic metre and range from 3.0 to 8.0 µg/m³, with a typical (median) reading of 3.5 µg/m³ and the 90th percentile reaching about 6.8 µg/m³.

The dataset shows uneven coverage: CO is captured at only one location, while the other pollutants benefit from four‑site sampling, providing a broader view of their spatial distribution. Although the number of rows (21) offers a snapshot rather than continuous monitoring, the freshness of all entries means the figures reflect current conditions in Kagoshima. Because measurements are limited to these stations and timestamps, actual citywide air quality can differ by neighborhood and time of day.
