What the data includes

The dataset for Iki contains measurements from a single monitoring location (one station row) and includes five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5), and sulfur dioxide (SO₂). All of the latest readings were recorded at the same time – 2026‑02‑10 22:00 UTC – so the data are fresh, having been updated within the past three days for each pollutant.

Across the five pollutants the observed values are very consistent. NO is reported as 0.0 ppm, while both NO₂ and NOX show a uniform concentration of 0.002 ppm. SO₂ also registers at 0.0 ppm. The only non‑zero measurement is PM2.5, which is recorded at 6.0 µg/m³. For each pollutant the minimum, median, maximum, 10th percentile and 90th percentile are identical to the single reported value, reflecting that there is currently just one data point per pollutant.

Because only one monitoring site contributes data, the coverage for Iki is limited to a specific address in 壱岐市郷ノ浦町本村触505‑5. This means spatial variation within the city cannot be captured by the present dataset; conditions elsewhere may differ from those at this location. The uniform timestamps and identical statistical summaries indicate that no historical spread or trend information is available yet, so any assessment of air quality must consider that the picture is based on a single, recent snapshot rather than a broader temporal record.
