Air quality today
The air quality in Kita is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 17.0 µg/m³ based on four valid observations reported through OpenAQ.
These measurements indicate that particulate matter levels are present but not extreme. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 dataset for Kita contains a single monitoring location – 北区王子5丁目29番 – and provides measurements for four key pollutants: nitrogen monoxide (NO) at 0.011 ppm, nitrogen dioxide (NO₂) at 0.022 ppm, total nitrogen oxides (NOX) at 0.033 ppm, and fine particulate matter (PM2.5) at 17.0 µg/m³. All four readings were recorded at the same moment, 2026‑02‑10 22:00 UTC, and each entry is flagged as having been updated within the past three days, indicating that the most recent data for this site are fresh.
Because only one station contributes to the record, the coverage in Kita is very limited; there are no additional rows or alternative locations to compare against. Consequently, the statistical summary for each pollutant shows no variation – the minimum, median, and maximum values are identical (NO 0.011 ppm, NO₂ 0.022 ppm, NOX 0.033 ppm, PM2.5 17.0 µg/m³), and the 10th‑percentile and 90th‑percentile figures match those same numbers. This uniformity reflects the single‑point nature of the data rather than a broader city‑wide pattern.
In practical terms, users should be aware that while the available measurements are recent, they represent only one spot in Kita and may not capture spatial differences across the district. The dataset does not contain older or unknown timestamps, so temporal gaps are not an issue here; however, the lack of multiple stations means that any assessment of overall air quality in Kita must consider this limited sampling scope.
