Air quality today
The air quality in Kani is classified as Good today. The primary pollutant identified is PM2.5, with a measured concentration of 9.0 µg/m³ based on four valid observations reported through OpenAQ.
Overall conditions meet the Good category criteria, and the data reflect the current state of fine particulate matter in the area. 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 Kani contains measurements of four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All four are reported from a single monitoring location identified as 可児市今渡１６８０, so the city’s coverage consists of one station row per pollutant. The most recent reading for each compound was recorded on 2026-02-10 at 22:00 UTC, and the system notes that this information was updated within three days, indicating a relatively fresh snapshot of ambient conditions.
Across the four substances the observed values are identical at their minimum, median and maximum points, showing no internal spread in the limited sample. NO registers 0.004 ppm, NO₂ 0.014 ppm, NOX 0.018 ppm and PM2.5 measures 9.0 µg/m³. Because each pollutant has only one recorded value, there is no range to describe variability; the data present a single point estimate rather than a distribution over time or space.
With just one reporting site, the dataset does not capture spatial differences that may exist across Kani, and the lack of multiple timestamps means trends cannot be assessed. The freshness of the latest entry suggests the information reflects conditions as of early February 2026, but any changes after that moment are not represented. Users should keep in mind that while these figures give a concrete snapshot for the listed location, broader city‑wide air quality may differ depending on local sources, weather patterns and time of day.

Data notes
The data shown for Kani reflects four valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. While this snapshot provides a current view of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
