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 Fuchu currently contains a single monitoring location, recorded at the address 府中市四谷４－１６－４. All four pollutants tracked by OpenAQ – nitrogen monoxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX) and fine particulate matter (PM2.5) – are represented in this row. The most recent reading for each pollutant was taken on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness category, so the data is relatively current.
Because there is only one station, the statistical spread for every pollutant is limited to a single value. NO registers at 0.008 ppm, NO2 at 0.025 ppm, NOX at 0.033 ppm and PM2.5 at 9.0 µg/m³; each of these figures serves as the minimum, median, maximum, 10th percentile and 90th percentile for its respective series. Consequently, there is no observable variation across time or space within this dataset, and any city‑wide assessment must acknowledge that conditions can differ in other neighborhoods or at later times.
In summary, Fuchu’s air‑quality record offers a snapshot from one site with up‑to‑date measurements for four key pollutants, but the lack of multiple stations means the coverage is narrow and the reported values cannot capture broader spatial patterns. Users should keep in mind that local conditions may change outside the moment captured on 2026‑02‑10 22:00 UTC.
