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 Kikuchi includes four measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All values come from a single monitoring location at 菊池市大字隈府字前田８７８番地１, so the city’s air‑quality picture is based on one station rather than a network of sites.
Each pollutant has only one recorded value, and that reading was last updated on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness window. Because there is just one row per pollutant, the reported range for every metric collapses to a single point: NO is consistently 0.001 ppm, NO₂ stays at 0.007 ppm, NOX at 0.008 ppm and PM2.5 at 12.0 µg/m³. The median, minimum and maximum values are identical for each pollutant, indicating no observed variability in the data set.
With only one monitoring site, spatial coverage is limited; conditions elsewhere in Kikuchi may differ from those captured at this address. Nevertheless, the timestamps show that the most recent measurements are current as of early February 2026, providing a snapshot of the city’s air quality at that moment rather than a longer‑term trend.
