What the data includes

The dataset for Kizugawa includes 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 a single monitoring location at 木津川市木津上戸１８番地, so the city‑wide picture is based on one row of data. The most recent update for every pollutant was recorded on 2026-02-10 22:00 UTC, meaning the information is fresh within the last three days.

Across the five pollutants the reported values are identical for each timestamp, showing no variation in the short‑term record. NO registers a flat 0.0 ppm, while both NO₂ and NOX are measured at 0.012 ppm. SO₂ appears at 0.001 ppm and PM2.5 is constant at 16.0 µg/m³. Because each pollutant has only one recorded observation, the minimum, median, maximum, 10th percentile and 90th percentile are all the same number, indicating no spread in the data set.

With just a single monitoring station, the coverage is limited to that specific address and does not capture spatial differences that may exist elsewhere in Kizugawa. The uniform timestamps also mean there is no recent trend information; any changes in air quality after 2026-02-10 are not reflected here. Users should keep in mind that conditions can vary by location and time, and the current snapshot provides only a narrow view of the city’s atmospheric composition.
