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 Kamaishi contains five recent measurement rows, each reporting the same set of five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All rows come from a single monitoring location at 釜石市新町６－５０ and were last updated on 2026-02-10 22:00 UTC, so the freshest data are just a few days old.
Across the five entries the observed values are extremely narrow. NO is consistently recorded as 0.0 ppm, while both NO₂ and NOX show a uniform reading of 0.002 ppm. SO₂ also remains at 0.0 ppm in every record. The only pollutant with a non‑zero measurement is PM2.5, which appears at exactly 1.0 µg/m³ for all rows. Because the minimum, median and maximum are identical for each compound, there is no detectable variation within this snapshot of Kamaishi’s air quality.
The coverage is limited to one sensor site, so spatial differences across the city are not captured in these data. Although the timestamps are recent, the lack of multiple stations means that conditions elsewhere in Kamaishi could differ from what the single location reports. Users should keep in mind that the dataset reflects a very specific point in time and place rather than a comprehensive city‑wide picture.
