Air quality today
The air quality in Ise is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 21.0 µg/m³ based on five valid observations reported through OpenAQ.
These measurements indicate that particulate matter levels are present but do not exceed the thresholds associated with higher categories. 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 Ise air‑quality dataset 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 come from a single monitoring site located at 伊勢市一之木5-5-3, so the city’s coverage in this record is limited to one station.
Each pollutant shows a single recorded value because the dataset includes only one row per compound. The NO concentration is 0.001 ppm, NO₂ is 0.013 ppm, NOX is 0.014 ppm and SO₂ registers at 0.0 ppm; PM₂.5 measures 21.0 µg/m³. For every pollutant the minimum, median and maximum are identical, indicating no observed variation across the reporting period. The most recent update for all five measurements was logged on 2026‑02‑10 at 22:00 UTC, which is within three days of today (2026‑02‑13), so the data are currently fresh.
Because only one monitoring location contributes to the record, spatial detail across Ise is lacking and any single reading may not reflect conditions elsewhere in the city. The uniform timestamps also mean there is no temporal spread to assess short‑term changes; each pollutant’s value is a snapshot rather than a trend. Users should keep in mind that while the data are up‑to‑date, they represent a very narrow slice of Ise’s overall air quality landscape.

Data notes
The data shown for Ise reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is considered “Updated within 3 days.” While this snapshot provides a current view of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may exist.
