What the data includes

The dataset for Kuwana pulls in measurements from two monitoring sites that together provide ten recent observations across six key pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of the values shown were recorded at the same moment, 2026‑02‑10 22:00 UTC, so the information is uniformly fresh, falling within the “updated within three days” window used by OpenAQ.

Across the two stations the recorded concentrations are fairly narrow. Carbon monoxide is reported at a single value of 0.6 ppm from the site in 桑名市繁松新田字宮之割42番地の1. Sulfur dioxide also appears as a single reading, 0.001 ppm, measured at 桑名市桑名市大字上野字笠松. The nitrogen‑oxide family shows low but variable levels: NO ranges from 0.0 to 0.009 ppm with a median of 0.0045 ppm; NO₂ spans 0.011 to 0.018 ppm, median 0.0145 ppm; and NOX covers 0.011 to 0.027 ppm, median 0.019 ppm. All three share the same location as the SO₂ reading. PM2.5 is reported as a constant 19.0 µg/m³ at that same site, indicating no observed fluctuation among the ten rows.

Because each pollutant is represented by only one or two stations, the spatial coverage within Kuwana is limited; conditions can differ in other neighborhoods or at other times of day. Nevertheless, the dataset provides a recent snapshot with consistent timestamps, allowing users to see the current range and typical values for each measured contaminant across the city’s available monitoring points.

Data notes

The data shown for Kuwana reflects ten valid measurements and is marked as Updated within 3 days, with the most recent update recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a current view of ambient conditions, but air quality can vary across different neighborhoods and times of day within the city, so values may not represent every location or moment precisely.
