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 Abiko currently draws from a single monitoring site located at 我孫子市湖北台４－３－１. All four pollutants tracked by OpenAQ – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX) and fine particulate matter (PM2.5) – are reported from this one station, so the spatial coverage is limited to that specific address.
Each pollutant shows a single recorded value because only one recent observation is available. NO registers at 0.002 ppm, NO₂ at 0.028 ppm, NOX at 0.03 ppm and PM2.5 at 24.0 µg/m³. For every metric the minimum, median and maximum are identical, indicating no variation in the data set beyond this lone measurement. The most recent timestamp for all four parameters is 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” freshness category used by OpenAQ.
Because there is just one row of data, the overall picture is narrow and reflects conditions at a single point in time rather than citywide trends. The uniformity of values means that typical or median concentrations cannot be distinguished from extremes – they are all the same reading. While the timestamps are recent, the lack of additional stations or historical entries limits any assessment of how air quality might differ across neighborhoods or change throughout the day. Users should keep in mind that actual conditions elsewhere in Abiko could vary from what this single‑site snapshot shows.
