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 Kaiserslautern contains measurements for seven common air‑quality constituents – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location, Kaiserslautern‑Rathausplatz, so the city’s overall coverage is limited to one station row per pollutant.
The most recent data are from 2026‑02‑10 17:00 UTC for CO, NO₂, O₃, PM10 and PM2.5, showing that these five pollutants have been updated within the last three days. The NO measurement is older, recorded on 2024‑03‑11 11:00 UTC, while SO₂ dates back to 2025‑04‑08 08:00 UTC. Because the timestamps vary, the overall picture reflects a mix of very fresh and relatively dated information.
Across the seven pollutants the reported values are all single observations with no spread: CO is 254.33 µg/m³, NO 3.60884905 µg/m³, NO₂ 15.6204967 µg/m³, O₃ 40.9307175 µg/m³, PM10 4.122954 µg/m³, PM2.5 exactly 1.0 µg/m³ and SO₂ 1.000125 µg/m³. Since each metric shows identical minimum, median and maximum figures, the dataset does not provide a range or variability for any pollutant at this site. The limited number of rows (seven) and the presence of older timestamps for NO and SO₂ mean that the current snapshot may not capture short‑term fluctuations elsewhere in the city, and conditions can differ by location and time.
