What the data includes

The Kuki air‑quality feed includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). The dataset contains eight recent rows of observations drawn from two monitoring stations, but all the reported values come from a single site at 久喜市本町７－９１３－１. Each pollutant’s most recent reading was logged on 2026‑02‑10 at 22:00 UTC and is flagged as updated within three days, so the data are current for that moment in time.

Across the eight rows, NO concentrations vary from a low of 0.002 ppm to a high of 0.016 ppm, with a median around 0.009 ppm. NO₂ shows a much tighter spread, ranging only between 0.020 and 0.022 ppm and centering near 0.021 ppm. NOX is broader, moving from 0.022 to 0.038 ppm and typically sitting at about 0.030 ppm. PM2.5 values sit in the narrow band of 11 to 12 µg/m³, with a median of roughly 11.5 µg/m³. The percentile‑10 and percentile‑90 figures confirm that each pollutant’s distribution is fairly compact, especially for NO₂ and PM2.5.

Because all four pollutants are reported from the same address, spatial coverage within Kuki is limited; conditions elsewhere in the city may differ. Nonetheless, the dataset provides a recent snapshot with fresh timestamps for every parameter, offering a clear picture of the current air‑quality levels at that specific location.

Data notes

The data shown reflects eight valid measurements and is updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. While this provides a current snapshot of Kuki’s air quality, conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
