Air quality today
The air quality in Hokota today falls into the Moderate category. The primary pollutant identified is PM2.5, with a measured concentration of 32.0 µg/m³ based on four valid observations. Data is shown via OpenAQ.
Overall conditions reflect a moderate level of fine particulate matter without additional pollutants reported. 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 Hokota includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX) and fine particulate matter (PM2.5). All of these values come from a single monitoring location at 鉾田市大字鉾田１３６７－３, so the city’s air‑quality picture is based on one station that reports four separate rows of data.
Each pollutant shows an identical statistical profile because only one observation is available. The NO reading stands at 0.006 ppm, with a minimum, median and maximum all equal to 0.006 ppm. NO₂ registers 0.012 ppm across the board, while NOX records 0.018 ppm for every metric. PM2.5 is reported as 32.0 µg/m³, again with no variation between its minimum, median or maximum values. Because there is only one measurement per pollutant, the spread (10th‑percentile to 90th‑percentile) is effectively zero, indicating that the dataset does not capture any temporal fluctuation.
The most recent update for every pollutant was logged on 2026-02-10 at 22:00 UTC, and each entry notes that it was “Updated within 3 days.” This means the data are fresh as of early February 2026, but the lack of additional rows or historic points limits insight into longer‑term trends. With only one monitoring site contributing all four pollutant rows, spatial coverage across Hokota is minimal; conditions elsewhere in the city may differ from those recorded at this single address. Users should keep in mind that the current snapshot reflects a very narrow point in time and space.

Data notes
The data shown reflects four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 22:00 UTC. While these figures provide a current snapshot of Hokota’s air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
