Air quality today
The air quality in Kariya is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements recorded by OpenAQ show a PM2.5 concentration of 21.0 µg/m³, based on four valid observations. No PM10 value is available for this assessment. 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
The dataset for Kariya contains measurements from a single monitoring location, giving four rows of data—one each for nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All values were recorded at the same site on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window, so the information reflects very recent conditions for each pollutant.
For the gaseous pollutants the reported concentrations are identical across the statistical summary: NO is measured at 0.001 ppm, NO₂ at 0.016 ppm and NOX at 0.017 ppm. Each of these figures represents the minimum, median and maximum observed during the reporting period, indicating no variation in the short‑term record for this station. The particulate matter reading shows a single value as well—21.0 µg/m³ for PM2.5—with the same lack of spread. Because only one sensor contributes data, there is no geographic diversity within the city; conditions elsewhere may differ from those captured at 刈谷市寿町1‑409.
Overall the dataset offers complete coverage of the four listed pollutants but from a very limited spatial sample. The timestamps are uniformly recent, yet the absence of multiple stations means the numbers cannot describe city‑wide patterns or fluctuations over time. Users should keep in mind that air quality can vary across neighborhoods and days, and the figures presented here represent a snapshot from a single point on 2026‑02‑10.
