The air quality in Harima is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 23.0 µg/m³ based on five valid observations.
Data are shown via OpenAQ and reflect the latest available readings for this location. 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
Harima’s OpenAQ feed currently contains five pollutant measurements from a single monitoring location in the town of 加古郡播磨町東本荘１－５－３０. The dataset includes nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Because there is only one row per pollutant, the station coverage is limited to this single site, meaning spatial variation across the city cannot be captured.
All five readings are very recent: the latest timestamps for NO, NO₂, NOX and PM2.5 are 2026‑02‑10 22:00 UTC, while SO₂ was last recorded at 2026‑02‑10 19:00 UTC. Each value is reported as a single point rather than a range – the minimum, median and maximum are identical for every pollutant. NO registers at 0.001 ppm, NO₂ at 0.017 ppm, NOX at 0.018 ppm, PM2.5 at 23.0 µg/m³ and SO₂ again at 0.001 ppm. Because the data set contains only one observation per pollutant, there is no spread to describe; the reported figures represent both the typical (median) and extreme values for the period covered.
The uniform freshness of the measurements indicates that the sensor feed has been updated within the last three days, but the lack of multiple stations or repeated observations means the picture is narrow. Conditions in Harima can differ across neighborhoods and over time, so while these numbers give a snapshot from one location on a specific day, they do not reflect broader city‑wide air quality patterns.

Data notes
The data shown reflects five valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. These readings provide a snapshot of current conditions in Harima, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
