Air quality today

The air quality in Kishiwada is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles), with a measured concentration of 25.0 µg/m³ based on five valid observations.

Data are shown via OpenAQ and reflect the latest available readings for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Kishiwada contains measurements from a single monitoring location (279‑2 Nishinouchi‑cho) and includes five common air‑quality pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All five compounds are represented, giving a basic chemical snapshot of the city’s ambient air at that site.

Each pollutant is reported with one value that serves as the minimum, median and maximum for the most recent 24‑hour period, indicating no observed variation in the data stream. NO registers at 0.005 ppm, NO₂ at 0.027 ppm, NOX at 0.032 ppm, PM2.5 at 25.0 µg/m³ and SO₂ at 0.001 ppm. Because the same timestamp—2026‑02‑10 22:00 UTC—is attached to every measurement, the data are uniformly recent, falling within the “updated within three days” freshness category.

With only one row per pollutant, coverage is limited to a single point in the city, so spatial differences across Kishiwada cannot be assessed from this set. The lack of spread between minimum and maximum values suggests either very stable conditions at that location during the reporting window or that the sensor has not captured variability yet. Consequently, while the dataset provides up‑to‑date concentrations for the listed pollutants, it offers a narrow view of overall city air quality and should be interpreted as a snapshot rather than a comprehensive picture.

Data notes

The data shown for Kishiwada is based on five valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and throughout the day, so values may not represent current or citywide conditions.
