Air quality today
The air quality in Izunokuni is classified as Good today. The primary pollutant identified is PM2.5, with a measured concentration of 6.0 µg/m³ based on two valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. 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 Izunokuni air‑quality record draws from a single monitoring site that supplies five pollutant measurements: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All five rows come from the same location, identified as 伊豆の国市田京山崎７４０－５.
The data for the gases are dated 2024‑11‑20 00:00 UTC, so they are more than a year old. In contrast, the particulate and sulfur readings were refreshed on 2026‑02‑10 22:00 UTC, which is within the last three days. This mix of timestamps means that while the most recent PM2.5 and SO₂ values reflect current conditions, the NO, NO₂ and NOX figures may no longer represent today’s atmosphere.
Across the five parameters the observed ranges are very narrow. NO registers a constant 0.0 ppm (minimum, median and maximum all zero). Both NO₂ and NOX show a single value of 0.005 ppm, with no variation between the 10th and 90th percentiles. PM2.5 is recorded at exactly 6.0 µg/m³ everywhere it was measured, again without spread. SO₂ likewise reads 0.0 ppm throughout. Because each pollutant has only one reported value, there is no statistical dispersion to describe.
Overall the dataset offers complete coverage of the listed pollutants but from just one station, and the freshness differs markedly between gas‑phase compounds (old) and particulate/sulfur measurements (very recent). Users should keep in mind that conditions can change across different parts of Izunokuni and over time, especially given the limited spatial and temporal resolution of the current records.

Data notes
The data shown for Izunokuni is based on two valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 22:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent current or city‑wide conditions.
