Air quality today

The air quality in Hino is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).

Measurements from OpenAQ show a PM2.5 concentration of 10.0 µg/m³ based on four valid observations. This reflects the latest data available for the city.

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 Hino includes measurements of four key air‑quality constituents: nitrogen monoxide (NO), nitrogen dioxide (NO₂), the combined oxidised nitrogen fraction (NOX) and fine particulate matter (PM2.5). All values come from a single monitoring site located at 日野市落川９４６番地先, so the city’s coverage in this snapshot consists of four rows – one for each pollutant – recorded at the same moment.

Each pollutant shows an identical timestamp of 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” freshness category. Because there is only one observation per compound, the reported minimum, median and maximum are all the same: NO registers 0.004 ppm, NO₂ 0.022 ppm, NOX 0.026 ppm and PM2.5 10.0 µg/m³. The lack of variation means no spread can be derived from this sample; the data represent a single point in time rather than an ongoing range.

Consequently, while the figures give a clear snapshot of current concentrations at that location, they do not capture spatial or temporal diversity across Hino. Conditions elsewhere in the city may differ, and future updates will be needed to build a broader picture of how these pollutants behave over time and across multiple sites.

Data notes

The data shown reflects four valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a brief overview of Hino’s current air quality; however, conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
