What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one monitoring location contributes to the dataset, recorded at Capitolo – New Brighton Middle School. The sole pollutant available is PM2.5, reported in micrograms per cubic metre. All three statistical measures—minimum, median and maximum—are identical at 4.87 µg/m³, indicating a single observation rather than a range of values.

Because the latest update timestamp is 2026-02-10 22:53 UTC, the data falls within the “last seven days” freshness category, showing that the most recent reading is fairly current. However, with just one row and no additional stations, coverage across Capitola is limited to this single point source. Consequently, while the figure of 4.87 µg/m³ reflects the latest measurement at that location, it does not capture spatial variation throughout the city or longer‑term trends. Users should keep in mind that conditions may differ elsewhere and at other times.

Data notes

The current air‑quality data for Capitola is based on a single valid measurement and was updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:53:16+00:00. This snapshot reflects conditions at one monitoring point at that time; actual pollutant levels can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single data point.
