Air quality today

The air quality in Anjo is currently classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 8.0 µg/m³ based on five valid observations from OpenAQ data.

Overall conditions meet the criteria for a Good rating, and no other pollutants are highlighted in the available dataset. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Anjo contains measurements from a single monitoring location (安城市池浦町茶筅木１) and includes five key air‑quality variables: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All five pollutant rows were recorded within the last three days, with the most recent timestamp being 2026-02-10 22:00 UTC, so the information is currently fresh.

Across the five pollutants the observed values are identical for each variable at this site. NO registers a concentration of 0.001 ppm, NO₂ 0.016 ppm, NOX 0.017 ppm and SO₂ also 0.001 ppm; PM2.5 measures 8.0 µg/m³. Because there is only one reporting station, the dataset does not provide a range of values – the minimum, median, 10th percentile and 90th percentile are all the same as the single reported figure for each pollutant.

The coverage therefore reflects a snapshot rather than a city‑wide picture. While the data are up‑to‑date, the lack of multiple stations means spatial variation within Anjo cannot be captured here. Users should keep in mind that conditions may differ across neighborhoods and at other times, as this dataset represents only one location and a single recent measurement per pollutant.

Data notes

The data shown for Anjo reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered “Updated within 3 days.” While these figures give a reliable snapshot of current conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may exist.
