Air quality today

The air quality in Akita today falls into the Moderate category according to the latest assessment. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 22.0 µg/m³. Data are shown via OpenAQ and are based on sixteen valid measurements.

Overall, conditions reflect a moderate level of particulate matter without additional pollutants reported. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Akita pulls in 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). Across the city there are 16 individual measurement rows drawn from three monitoring sites, so each pollutant is not necessarily represented at every location. The most recent values for all pollutants were recorded on 2026‑02‑10 at 22:00 UTC, which falls within a three‑day freshness window.

For gases, the NO readings are uniformly zero across the available rows, with a maximum of just 0.005 ppm and a median of 0 ppm. NO₂ shows a tighter band, ranging from 0.003 to 0.009 ppm and centering on a median of 0.004 ppm. NOX follows a similar pattern, spanning 0.003–0.014 ppm with a median of 0.004 ppm. Sulfur dioxide is also low, varying between 0 and 0.006 ppm and medially sitting at 0.001 ppm. Carbon monoxide is reported from only one site (秋田市茨島１－４－７１) and all three rows for CO share the same value of 0.3 ppm.

Particulate matter shows a broader distribution: PM2.5 values range from 14 to 22 µg/m³, with a median of 16 µg/m³ and the 10th‑percentile at about 14.4 µg/m³ rising to a 90th‑percentile near 20.8 µg/m³. Because PM2.5 is measured at all three stations while CO appears at just one, the coverage for gases is uneven. Overall, the data are recent but limited in spatial breadth; conditions can differ across neighborhoods and times not captured by these rows.
