What the data includes

The Kanoya data set contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location at 鹿屋市新栄町６４９, so the station count is one row per pollutant. The most recent reading for each pollutant was recorded on 2026-02-10 22:00 UTC, which means the data are all updated within the last three days.

Across the five pollutants the observed ranges are very narrow because every measurement reports a single value rather than a distribution of many observations. NO, NO₂ and NOX each show a constant concentration of 0.0 ppm, while PM2.5 is consistently measured at 4.0 µg/m³ and SO₂ at 0.001 ppm. The median, minimum and maximum values are identical for each pollutant, indicating no variability in the reported data set.

Because only one monitoring site contributes to the city’s profile, spatial coverage is limited; conditions elsewhere in Kanoya may differ from those captured at this point. Nevertheless, the timestamps confirm that all five pollutants have recent entries, so the snapshot reflects the latest available information rather than outdated or unknown records.
