Air quality today
The air quality today in the city is classified as Good. The main pollutant identified is PM10, and measurements show a PM10 concentration of 2.0 µg/m³ based on two valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 dataset for this city contains measurements for two key pollutants, nitrogen dioxide (NO2) and particulate matter 10 µm or smaller (PM10). All observations come from a single monitoring location, ZIERBANA, which contributes two rows of data—one row per pollutant. The most recent reading for each pollutant was recorded on 2026‑02‑09 at 15:00 UTC, and the system flags both as having been updated within the past seven days, indicating that the information is relatively fresh.
For NO2, every reported value is identical across the available row: a minimum, median, and maximum of 4.0 µg/m³, with the 10th‑percentile and 90th‑percentile also at 4.0 µg/m³. This uniformity shows that, at the time of measurement, NO2 levels were stable and did not vary within the dataset. PM10 exhibits a similar pattern, with all statistical points—minimum, median, maximum, 10th‑percentile and 90th‑percentile—equal to 2.0 µg/m³. The lack of spread in both pollutants suggests that the single monitoring site captured a consistent snapshot rather than a range of conditions.
Because the coverage is limited to one station, the data do not reflect spatial variations across the wider urban area. While the timestamps are recent, the small number of rows means that temporal trends or differences between neighborhoods cannot be assessed from this set alone. Users should keep in mind that air quality can change throughout the city and over time, and additional monitoring locations would be needed for a more comprehensive picture.
