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 Kushiro contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOₓ), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these are reported from a single monitoring location at 釧路市昭和中央3丁目12番2号, so the city’s coverage in this snapshot is limited to one station.
The most recent values were recorded on 2026-02-10 at 22:00 UTC and each pollutant was flagged as updated within three days, indicating that the data are relatively fresh. Because there is only one row per pollutant, the reported statistics show no variation: the minimum, median, 10th percentile, 90th percentile and maximum are identical for each substance. NO sits at 0.001 ppm, NO₂ at 0.007 ppm, NOₓ at 0.008 ppm, SO₂ also at 0.001 ppm, while PM2.5 is measured at 10.0 µg/m³.
With a single measurement site the dataset cannot capture spatial differences across Kushiro, and the lack of multiple observations means there is no spread to describe trends or day‑to‑day fluctuations. Users should keep in mind that air quality can change by location and over time, so this snapshot provides only a narrow view of current conditions at one point in the city.
