Air quality today
The air quality in Hasuda today falls into the Moderate category according to the latest assessment. The primary pollutant identified is PM2.5, with a measured concentration of 21.0 µg/m³. Four valid measurements contributed to this evaluation, and no PM10 reference value is available for comparison.
Overall conditions reflect the reported moderate rating based on the available data. 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 Hasuda includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All values come from a single monitoring point identified as 蓮田市蓮田５－３０, so the city’s air‑quality picture is based on one location rather than a network of stations.
Each pollutant has only one recorded row, giving a total of four rows in the current feed. The most recent update for every parameter was logged at 2026-02-10 22:00 UTC, which is within three days of today’s date (2026-02-13). This means the data are fresh, but because there is only one sensor the spatial coverage across Hasuda is very limited.
The reported concentrations show no variation across the dataset. NO is consistently measured at 0.002 ppm, NO2 at 0.022 ppm, NOX at 0.024 ppm and PM2.5 at 21.0 µg/m³; each pollutant’s minimum, median and maximum values are identical. Consequently, there is no observable spread or range to describe typical versus extreme conditions for this site. The uniformity of the numbers reflects the single‑point sampling rather than a broader city‑wide trend.
In summary, Hasuda’s publicly available air‑quality data provide up‑to‑date readings for four key pollutants, but they are derived from only one monitoring location and contain a single value per pollutant, offering limited insight into how conditions may differ across other parts of the city or over time.

Data notes
The data shown for Hasuda reflects four valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a recent view of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
