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 Pieterlen draws on a single monitoring location that records five key atmospheric variables: PM1, PM2.5, relative humidity, temperature and particle concentration (UM003). All of these pollutants are present in the data feed, and each measurement was last updated on 2026-02-04 06:00 UTC, which falls within the “updated within 30 days” freshness window.
Because the information comes from just one station, the reported values show no internal variation – the minimum, median and maximum are identical for every parameter. PM1 is measured at 11.385454559326172 µg/m³, while PM2.5 registers 28.224909071488813 µg/m³. Relative humidity stands at 64.60709096735174 %, temperature is recorded as 6.06890906420621 °C, and the UM003 particle count is 752.5305442116478 particles/cm³. These figures represent the sole snapshot available for the city at the given timestamp.
The limited spatial coverage means that the dataset cannot capture differences across neighborhoods or changes over time; any fluctuations in air quality throughout Pieterlen will not be reflected here until new measurements are logged. Consequently, while the data provides a current point‑in‑time view of several pollutants, it offers no insight into trends, variability or broader citywide conditions. Users should keep in mind that actual atmospheric conditions may differ elsewhere in the municipality and at other times.
