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 Goto contains measurements from a single monitoring location (五島市福江町504‑1) and includes five common air‑quality pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of the most recent readings were recorded at the same moment – 2026‑02‑10 22:00 UTC – and each entry is flagged as having been updated within the past three days, so the data are currently fresh.
Across the five pollutants the observed values show very little variation. NO, NOX and SO₂ all read exactly 0.0 ppm, while NO₂ registers a constant 0.001 ppm. The PM2.5 concentration is uniformly 4.0 µg/m³. Because each pollutant has only one recorded value (minimum, median and maximum are identical), the dataset does not reveal any spread or day‑to‑day fluctuation for this site.
With just one monitoring station contributing a single row of data per pollutant, coverage is limited to that specific point in the city. Consequently, while the numbers give an up‑to‑date snapshot for 五島市福江町504‑1, they cannot represent conditions elsewhere in Goto or capture changes over time until new measurements are added.
