Air quality today

The air quality in Atami is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 1.0 µg/m³ based on four valid readings collected by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Atami contains measurements of four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5) – all reported from a single monitoring site located at 熱海市水口町13-15. Each pollutant has a recent timestamp; the latest update for every parameter was recorded on 2026‑02‑10 22:00 UTC, which is within three days of today’s date and therefore reflects current conditions.

Because only one station contributes data, the coverage across the city is limited to that specific neighbourhood. The reported values show no variability over time: NO consistently reads 0.0 ppm (minimum, median and maximum are all zero), while both NO₂ and NOX are fixed at 0.002 ppm for every statistic measured. PM2.5 likewise remains constant at 1.0 µg/m³ across its minimum, median and maximum. This uniformity means the dataset does not capture any range or spread in pollutant levels for Atami; instead it provides a single snapshot of each contaminant at one location.

Consequently, while the information is fresh and includes the key gases and particles typically tracked for air quality, the single‑site nature limits how well it represents conditions elsewhere in the city. Users should keep in mind that concentrations can differ by neighbourhood and time of day, even though the present data set offers a clear, up‑to‑date picture for the monitored spot.

Data notes

The data shown reflects four valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T22:00:00+00:00. These values provide a recent snapshot of Atami’s air quality but note that conditions can differ across neighborhoods and change throughout the day, so this overview may not represent every location or moment within the city.
