Air quality today

The air quality in Ibigawa is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 7.0 µg/m³ based on five valid observations recorded by OpenAQ. No other pollutants are highlighted for this period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Ibigawa contains measurements of five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location in the area of 上南方字森本, 揖斐郡揖斐川町. The most recent reading for each pollutant was recorded on 2026-02-10 22:00 UTC, which is within three days of today and therefore reflects current conditions.

Across the single row of data, NO registers a constant value of 0.0 ppm, while both NO₂ and NOX show identical readings of 0.006 ppm with no variation (minimum, median and maximum are all 0.006). PM2.5 is reported at 7.0 µg/m³, again without any spread in the recorded values. SO₂ also records a uniform 0.0 ppm. Because each pollutant’s statistics show a single value rather than a range, the dataset does not capture variability over time or space.

With only one monitoring station, the coverage for Ibigawa is limited to that specific site, so conditions elsewhere in the city may differ from what is shown here. The data are fresh, but the lack of multiple rows or stations means the picture is narrow and should be interpreted as a snapshot rather than a comprehensive view of air quality across the whole municipality.

Data notes

The data shown reflects five valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. These values provide a current snapshot of Ibigawa’s air quality but may not represent conditions everywhere in the city or at every moment, as concentrations can differ by location and time.
