What the data includes

The dataset for Mima includes measurements of five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location at 美馬市脇町大字猪尻字建神社下南７３, so the city’s coverage is limited to one station row for each pollutant.

The most recent reading for every pollutant was recorded on 2026-02-10 22:00 UTC, and all five entries fall within the “last three days” freshness bucket, indicating that the data are up‑to‑date. NO shows a uniform value of 0.0 ppm, while both NO₂ and NOX register exactly 0.006 ppm at the same timestamp. PM2.5 is reported as 7.0 µg/m³, and SO₂ again reads 0.0 ppm. Because each pollutant’s minimum, median and maximum are identical, there is no observed variability in this snapshot; the spread for every metric is effectively zero.

These numbers illustrate a very narrow temporal window – only one recent measurement per pollutant – and a spatial limitation to a single site. Consequently, while the data are fresh, they do not capture any day‑to‑day fluctuations or differences across neighborhoods within Mima. Users should keep in mind that air quality can change with location and time, and the current dataset provides just a brief point‑in‑time picture from one monitoring spot.
