Air quality today

The air quality today in Fukuchiyama is classified as Moderate. The primary pollutant identified is PM2.5, which refers to fine particulate matter measured in the atmosphere.

Measurements show a PM2.5 concentration of 12.0 µg/m³ based on five valid observations reported through OpenAQ. This reflects the current level of fine particles present in the local air. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Fukuchiyama contains measurements from a single monitoring site located at 福知山市岡ノ町１７５－３. Five pollutants are recorded: nitrogen monoxide (NO) at 0.001 ppm, nitrogen dioxide (NO₂) at 0.007 ppm, total nitrogen oxides (NOX) at 0.008 ppm, fine particulate matter (PM2.5) at 12.0 µg/m³, and sulfur dioxide (SO₂) at 0.0 ppm. All values are drawn from one row per pollutant, so the station coverage is limited to a single point in the city rather than a network of locations.

The most recent update for each pollutant was on 2026-02-10 22:00 UTC, which falls within the “updated within 3 days” freshness category and therefore represents current conditions as of today (2026‑02‑13). Because there is only one observation per pollutant, the statistical spread is effectively zero; the minimum, median, and maximum values are identical for each substance. This uniformity means that the data provide a snapshot rather than a range of variability across time or space.

Given the single‑site configuration, the dataset cannot capture spatial differences within Fukuchiyama, and any temporal trends would require additional measurements over successive days. Nevertheless, the presence of all five common air‑quality indicators offers a complete chemical profile for the location at the recorded moment, with each pollutant reported in its standard unit (ppm for gases, µg/m³ for PM2.5). Users should keep in mind that conditions elsewhere in the city may differ from those measured at this lone station.

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. While this snapshot provides a current view of Fukuchiyama’s air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
