What the data includes

The dataset for Pickering pulls in five recent observations from a single monitoring site. All five pollutants are reported with the same most‑recent timestamp of 2026-02-10 22:00 UTC, so the data are uniformly fresh but come from only one location.

PM1 and PM2.5 are both recorded as 0.0 µg/m³, with no variation across the five rows (minimum, median and maximum all equal zero). Relative humidity is reported at 42.70083357493082 % and temperature at 24.59016688664754 °C; each of these variables also shows a single value across the dataset, indicating no observed spread. The particle count measured as UM003 stands at 7.200166670481365 particles/cm³, again with identical min‑med‑max values.

Because the data come from only one station, they provide a very narrow snapshot of city conditions. There is no range or distribution to describe variability over time or across different parts of Pickering, and the lack of multiple readings means any single measurement may not reflect broader patterns in the city.
