Air quality today
The air quality in Gotsu is rated as Good today. The primary pollutant identified is PM2.5 (fine particles).
Measurements from five valid observations show a PM2.5 concentration of 6.0 µg/m³. 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 Gotsu contains a single monitoring location (江津市江津町１５２５) that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO2). All rows were last refreshed on 2026‑02‑10 at 22:00 UTC, so the most recent measurements are less than three days old.
Across the five pollutants the recorded values show very little variation because each metric has only one observation. NO, SO2 and the NO‑related compounds (NO2, NOX) all read zero or 0.002 ppm, with both the minimum, median and maximum equal to those figures. PM2.5 is the only pollutant that registers a non‑zero concentration, consistently measured at 6.0 µg/m³. Because there is just one station, the range (minimum to maximum) for each pollutant collapses to a single point, and the 10th and 90th percentiles match the median.
The coverage is therefore limited: only one row contributes data for all five pollutants, and no older or unknown‑timestamp entries are present. This means that while the snapshot is recent, it reflects conditions at a single site rather than citywide averages, and actual air quality in other parts of Gotsu may differ from these values.

Data notes
The data shown for Gotsu reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC, meaning it is updated within three days. This snapshot provides a current view of ambient air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
