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 air‑quality record for Pernik currently draws from four separate sensor readings, one for each of the measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter 10 µm or smaller (PM10) and sulfur dioxide (SO2). All four observations come from a single monitoring site identified as AMS Center‑Pernik, so the dataset reflects conditions at that location only. The most recent update for every pollutant was recorded on 2026-02-10 19:00 UTC, meaning the data are fresh within the last three days.
Across the four rows the values show no variation; each pollutant has a single reported figure that also serves as its minimum, median and maximum. CO registers at 430.0 µg/m³, NO2 at 60.63 µg/m³, PM10 at 25.8 µg/m³ and SO2 at 28.63 µg/m³. Because the dataset contains only one measurement per pollutant, there is no spread to describe – the 10th and 90th percentiles match the single value in each case.
The coverage is therefore limited: with just one station contributing data, spatial differences across Pernik are not captured, and any temporal changes after the last update are absent. While the timestamps indicate that the information is recent, the lack of multiple rows or historic points means the current snapshot cannot illustrate how concentrations fluctuate throughout the day or week. Users should keep in mind that conditions elsewhere in the city may differ from those recorded at AMS Center‑Pernik, and future updates will be needed to build a fuller picture of local air quality.

Data notes
The data shown for Pernik reflects three valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T19:00:00+00:00. While this snapshot provides a current view of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
