Air quality today
The air quality in Handa is rated as Moderate today. The primary pollutant identified is PM2.5, with a measured concentration of 16.0 µg/m³. Data are based on five valid measurements and are shown via OpenAQ.
Overall conditions reflect the moderate classification without additional detail. 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 Handa includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location at 半田市東洋町１－３－６, so the city’s air‑quality picture is based on one station row per pollutant. The most recent reading for each compound was recorded on 2026-02-10 22:00 UTC, and every entry carries a “Updated within 3 days” flag, indicating that the data are fresh as of the latest download.
Across the five pollutants the observed concentrations show virtually no variation because each metric has only one reported value. NO is measured at 0.002 ppm, NO₂ at 0.018 ppm and NOX at 0.020 ppm; all three share identical minimum, median and maximum values, reflecting a single data point rather than a range of observations. PM2.5 registers 16.0 µg/m³, again with no spread between its statistical percentiles. SO₂ is reported as 0.0 ppm, indicating that at the time of measurement no detectable sulfur dioxide was present at this site.
Because the coverage relies on just one sensor location, the dataset does not capture spatial differences that may exist elsewhere in Handa. The uniform timestamps and lack of multiple rows mean there is no temporal depth to assess changes over days or weeks. Consequently, while the numbers give a snapshot of current conditions at the specified address, they cannot represent city‑wide variability or trends. Users should keep in mind that air quality can differ by neighborhood and time of day, and additional monitoring points would be needed for a more comprehensive view.
