Air quality today

The air quality in Higashiōsaka is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 20.0 µg/m³ based on eleven valid observations reported through OpenAQ.

No additional pollutants are highlighted for today, and the data reflect the latest available readings. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Higashiōsaka draws from three monitoring sites that together contribute sixteen recent observations across six key pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). For most gases the latest reading was recorded on 2026-02-10 22:00 UTC, while CO is only as recent as 2026-02-04 03:00 UTC, indicating a slightly older snapshot for that pollutant.

Across the three stations the measured concentrations show a fairly narrow spread. NO ranges from a low of 0.001 ppm to a high of 0.008 ppm with a median of 0.002 ppm; NO₂ varies between 0.010 and 0.026 ppm, centering around 0.023 ppm; NOX spans 0.012–0.034 ppm with a median of 0.024 ppm. PM2.5 values are the most variable in mass terms, ranging from 1.0 to 20.0 µg/m³ and clustering near a median of 18 µg/m³, while SO₂ stays low at 0.0–0.003 ppm with a typical value of 0.001 ppm. CO is constant in this snapshot at 0.3 ppm across all reported rows.

The data set includes ten entries that are less than three days old, one entry from the past month and five older records, so most of the information reflects very recent conditions but a handful of observations are dated. Because only three stations contribute, spatial coverage is limited; air quality can differ in other parts of Higashiōsaka or change rapidly between measurement times. Users should keep in mind that the picture presented here captures specific points in time and location rather than a city‑wide continuous record.

Data notes

The data shown reflects eleven valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of air quality in Higashiōsaka, but conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
