Air quality today
The air quality in Ibaraki is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements from five monitoring stations show a PM2.5 concentration of 17.0 µg/m³. No PM10 value is available for this assessment. Data is shown via 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 dataset for Ibaraki includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these come from a single monitoring location at 茨木市駅前３－８－１３, so the city’s air‑quality picture is based on one row of data rather than a network of stations.
Each pollutant shows a single recorded value because the minimum, median and maximum are identical. NO registers 0.0 ppm, while both NO₂ and NOX are reported at 0.014 ppm. PM2.5 measures 17.0 µg/m³ and SO₂ is at 0.001 ppm. Because there is only one observation per pollutant, the spread (10th‑90th percentile) is also flat, indicating no variation within this snapshot. The most recent update for every parameter was on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness window used by the source.
With just one sensor feeding all five pollutants, coverage across the city is limited; conditions can differ in other neighborhoods or at different times of day. The data are current as of early February 2026, but the lack of multiple rows means there is no historical depth or spatial diversity to assess trends or localized differences. Users should keep in mind that while these figures give a precise reading for the specific site and moment, they do not capture the full variability of air quality throughout Ibaraki.

Data notes
The data shown reflects five valid measurements and was updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00. While this provides a current snapshot of Ibaraki’s air quality, conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
