Air quality today

The air quality today in Gifu is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 11.0 µg/m³ based on fifteen valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Gifu data set contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from three monitoring stations, giving a total of fifteen recent rows in the feed. The most recent update for each pollutant was recorded on 2026-02-10 22:00 UTC, so the data are all less than three days old.

Across the three sites the observed concentrations show a narrow range for the nitrogen gases. NO is reported at exactly 0.0 ppm at the station in 八ツ寺町1‑7, while NO₂ varies between 0.004 and 0.008 ppm (median 0.004 ppm) and NOX spans 0.004 to 0.008 ppm with a median of 0.005 ppm, all measured at the same location. PM2.5 values are higher and more variable: the site in 八ツ寺町1‑7 records concentrations from 5.0 up to 11.0 µg/m³, with a median of 7.0 µg/m³ and the 10th–90th percentile range lying between 5.4 and 10.2 µg/m³. Sulfur dioxide is uniformly absent in the current feed, showing 0.0 ppm at the station in 福光東３‑１９.

The dataset therefore offers a complete snapshot for nitrogen oxides and particulate matter but provides only a single zero reading for SO₂, indicating limited coverage for that pollutant. Because all rows are recent, the numbers reflect conditions on the morning of 2026-02-10, yet spatial variation is possible since the three stations are located in different parts of the city. Users should keep in mind that air quality can change throughout the day and across neighborhoods, so these figures represent a specific moment rather than a continuous trend.

Data notes

The data shown reflects 15 valid measurements and is Updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00. These values represent a citywide snapshot; air quality can differ across neighborhoods and change throughout the day, so conditions you experience locally may not match this summary.
