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 Casalmaggiore currently contains six recorded rows covering a single monitoring site. It provides measurements for six pollutants: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. The most recent values were all captured on 2026-02-10 at 21:00 UTC for PM1 (33.33 µg/m³), PM2.5 (58.98 µg/m³), relative humidity (72.39 %), temperature (11.93 °C) and UM003 (8 120.43 particles/cm³). The only older entry is the PM10 reading, which dates back to 2025-01-13 at 23:00 UTC with a concentration of 19.90 µg/m³.
All six pollutants show a single recorded value, so each metric’s minimum, median and maximum are identical. This means there is no observed spread within the dataset; for example, PM1 sits exactly at 33.33 µg/m³ and temperature remains steady at 11.93 °C across the available record. Because only one station contributes data, spatial coverage across Casalmaggiore is limited to that point, and temporal depth is shallow—most parameters are fresh within the last few days, while PM10 lags by more than a year.
In practical terms, users can rely on very recent information for five of the six pollutants, but should treat the PM10 figure as outdated. The uniformity of values indicates that the current snapshot does not capture variability over time or across different parts of the city, so conditions may differ elsewhere or change after the last update.
