Air quality today
The air quality in Sokolov today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 4.3 and a PM10 reference value of 3.5, based on five valid observations recorded via OpenAQ.
Overall conditions meet the criteria for a Good rating according to the provided assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Sokolov dataset contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or smaller (PM10), particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO2). All values come from a single monitoring row, so the city’s air‑quality picture is based on one station rather than a network of sites.
The freshest data are from 2026‑02‑10 14:00 UTC for five pollutants (NO2, O3, PM10, PM2.5 and SO2), while the NO measurement dates back to 2024‑03‑11 10:00 UTC, making it considerably older than the others. Across the recent records the reported concentrations are uniform: each pollutant shows a single value with no observed spread – the minimum, median, maximum, 10th percentile and 90th percentile are identical for every component (NO 0.6 µg/m³, NO2 9.8 µg/m³, O3 50.1 µg/m³, PM10 3.5 µg/m³, PM2.5 4.3 µg/m³, SO2 4.0 µg/m³). This lack of variability indicates that the dataset captures only a snapshot rather than a range of conditions.
Because there is just one row and most timestamps are recent except for NO, the coverage is limited both spatially and temporally. Consequently, while the numbers give an exact reading at the moment they were logged, they do not reflect how concentrations may change across different parts of Sokolov or over longer periods. Users should keep in mind that city‑wide air quality can differ from this single point observation.
