Air quality today
The air quality in Stěžery is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of approximately 33.6 µg/m³ based on five valid observations reported through OpenAQ.
Data for other pollutants are not available at this time. 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 Stěžery air‑quality record consists of a single monitoring location, so all data come from one row in the OpenAQ feed. Five pollutants are reported at this site: PM1, PM2.5, relative humidity, temperature and particle count (UM003). Each parameter shows a single value that was last updated on 2026-02-10 18:00 UTC, meaning the most recent observations are just under two days old and fall within the “updated within 3 days” freshness category.
For the particulate matter fractions, PM1 registers at 15.708 µg/m³ while PM2.5 is measured at 33.583 µg/m³; both values are identical to their respective minima, medians and maxima because only one reading exists. Relative humidity is recorded at 85.938 % and temperature at 5.614 °C, again with no variation across statistical summaries. The particle‑count sensor (UM003) reports 757.042 particles per cm³, also without spread.
Because the dataset contains just one row, there is no range or distribution to describe for any pollutant – each metric has a single point value rather than a spectrum of measurements over time or space. Consequently, while the data are fresh, they provide only an instantaneous snapshot of conditions at the Stěžery station and cannot capture temporal fluctuations or differences across the broader city area. Users should keep in mind that air‑quality can change throughout the day and between neighborhoods, so this single‑point record represents a limited view of overall city conditions.

Data notes
The dataset for Stěžery includes five valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑10 at 18:00 UTC. These figures represent a snapshot of ambient conditions across the city; air quality can differ by specific location and time of day, so values may not reflect conditions everywhere or at every moment.
