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 air‑quality feed for Higashikurume currently includes four measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX) and fine particulate matter (PM2.5). All data come from a single monitoring location at 東久留米市中央町６－９－１, so the dataset consists of one row per pollutant. The most recent update for every parameter was recorded on 2026‑02‑10 at 22:00 UTC, meaning the latest values are less than three days old.
Across the four pollutants the reported concentrations show no variation within the available sample. NO is consistently measured at 0.005 ppm, NO₂ at 0.025 ppm and NOX at 0.030 ppm; each of these figures represents the minimum, median and maximum observed value. PM2.5 is recorded as a steady 13.0 µg/m³ with identical statistics for its range. Because only one sensor contributes data, there is no spread to describe – the dataset reflects a single point in space rather than city‑wide coverage.
The limited spatial coverage means that while the timestamps are fresh, the information does not capture possible differences across neighborhoods or times of day. Users should keep in mind that conditions elsewhere in Higashikurume may differ from those at the central monitoring site, and that any analysis based on these figures represents a snapshot rather than a comprehensive view of the city’s air quality.
