Air quality today
The air quality in Matsusaka is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 21.0 µg/m³ based on five valid observations reported through OpenAQ. No PM10 reference value is available for this assessment. 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 dataset for Matsusaka includes five measured 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 location at 松阪市久保町276, so the station count is one row for each pollutant. The most recent reading for every compound was recorded on 2026-02-10 22:00 UTC, which falls within the “updated within three days” window and therefore represents very fresh data for the city.
Across the five pollutants the observed values are tightly clustered. NO, SO₂ and the NO‑related species (NO₂ and NOX) each show a single measurement of 0.0 ppm for NO and SO₂, and 0.011 ppm for both NO₂ and NOX; the minimum, median, maximum, 10th percentile and 90th percentile are all identical, indicating no variation in the recent sample set. PM2.5 is reported at a constant 21.0 µg/m³ with the same uniform statistics across all percentiles. Because only one monitoring site contributes data, there is no spread to describe temporal or spatial variability within Matsusaka; the dataset therefore reflects a snapshot rather than a range of conditions.
In practical terms, the information available for Matsusaka is limited to a single point measurement that was taken just three days ago. While this provides an up‑to‑date picture of the five listed pollutants at that specific location, it does not capture differences that might exist elsewhere in the city or over longer periods. Users should keep in mind that air quality can change across neighborhoods and times of day, and the current dataset offers only a narrow view of those dynamics.

Data notes
The data shown for Matsusaka is based on five valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. These readings provide a snapshot of current conditions, but air quality can differ across neighborhoods and change throughout the day, so localized values may vary from what is displayed here.
