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 data for Minami includes five measured pollutants—nitric oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂)—collected from a single monitoring location (one row of station data). For each pollutant the dataset provides a minimum, median and maximum value that are all identical, indicating no observed variation over the reporting period. NO registers at 0.0 ppm, while both NO₂ and NOX show a consistent concentration of 0.002 ppm. PM2.5 is recorded at 11.0 µg/m³ and SO₂ at 0.001 ppm.
The timestamps reveal that the nitrogen‑oxide series were last updated on 2026-01-30 00:00 UTC, whereas the particulate matter and sulfur dioxide measurements are more recent, with a last update of 2026-02-10 22:00 UTC. This means the freshest data for PM2.5 and SO₂ is about two weeks newer than that for NO, NO₂ and NOX. Because only one monitoring site contributes all rows, spatial coverage across Minami is limited; conditions elsewhere in the city may differ from those captured at this single point.
Overall, the dataset shows a narrow numeric range (each pollutant’s values are constant) and a modest temporal spread, with half of the pollutants updated within the last month and the other half over two weeks older. Users should keep in mind that the information reflects conditions at one specific address (海部郡美波町西の地字魚呑３４－１) and may not represent the full variability of air quality across Minami.

Data notes
The data shown reflects five valid measurements and is marked as Updated within 30 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a brief overview of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
