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 Izumo includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All of these come from a single monitoring location at 出雲市塩冶町２２３－１, so the city’s coverage in this snapshot is limited to one station. The most recent update for every pollutant was recorded on 2026-02-10 at 22:00 UTC, meaning the data are fresh within the last three days.
Across the four pollutants the observed values show virtually no variation because each metric has only one reported reading. NO registers a constant 0.0 ppm, while both NO₂ and NOX are measured at 0.002 ppm. PM2.5 is recorded at 2.0 µg/m³. For each pollutant the minimum, median, maximum, 10th percentile and 90th percentile are identical to the single reported value, indicating a zero spread in this dataset. Because there is only one row per pollutant, no broader range or trend can be derived from these numbers alone.
The limited station count means that spatial differences within Izumo are not captured; conditions could differ elsewhere in the city or at other times. While the timestamps are recent, the lack of multiple observations restricts any assessment of variability over time or across locations. Users should keep in mind that this snapshot provides a point‑in‑time view from one site rather than a comprehensive picture of air quality throughout Izumo.
