What the data includes

Cloverdale’s OpenAQ feed currently provides data for three measured pollutants: PM2.5, relative humidity and temperature. The dataset contains nine recent observations (updated within the last seven days) across four distinct monitoring stations, giving a modest snapshot of conditions in the city. The most recent timestamp for each pollutant is 2026‑02‑11 00:00 UTC, so all values are fresh as of that date.

For PM2.5 the sensor at the NW Cloverdale site reports an average concentration of 9.15 µg/m³. Across the nine recent rows the recorded values range from a low of 7.2 µg/m³ to a high of 36.0 µg/m³, with the 10th percentile at 8.29 µg/m³ and the 90th percentile at 27.0 µg/m³. The median (13.0 µg/m³) sits nearer the lower end of the spread, indicating that most recent readings are below the upper tail of the distribution.

Relative humidity is represented by a single recent row from the same NW Cloverdale location, showing a constant value of 88.11 % for the minimum, median and maximum, as well as the 10th and 90th percentiles. Temperature also comes from one recent observation at that site, with a uniform reading of 12.27 °C across all statistical measures.

These numbers illustrate two clear points: first, PM2.5 has broader coverage with multiple rows capturing a range of values, while humidity and temperature are each based on only one recent measurement, limiting insight into variability over time or space. Second, the data are all current to early February 2026, but the sparse sampling for humidity and temperature means city‑wide conditions could differ in other neighborhoods or at later times.
