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 Kaga includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All of these come from a single monitoring location at 加賀市大聖寺南町二２１, so the city’s air‑quality picture is based on one station row per pollutant. The most recent readings were recorded on 2026-02-10 22:00 UTC, which is within three days of today (2026‑02‑13), indicating that the data are currently fresh.
Across the four pollutants the values are identical for each metric because only one observation exists. NO was measured at 0.001 ppm, NO₂ at 0.009 ppm and NOX at 0.010 ppm; the PM2.5 concentration is 7.0 µg/m³. For every pollutant the minimum, median (50th percentile), 10th‑percentile and 90th‑percentile values are the same as the single recorded value, so there is no observed spread or variability in this snapshot. Because the dataset contains just one row per pollutant, it cannot reveal day‑to‑day fluctuations or spatial differences within Kaga.
The limited coverage means that while the timestamps are recent, the information represents only a narrow point in time and space. Consequently, conditions elsewhere in the city or at other times may differ from what these numbers show. Users should keep in mind that the current snapshot provides a concise but very localized view of Kaga’s air quality, with no historical depth or broader geographic sampling available at present.
