Air quality today
The air quality in Harzgerode is assessed as Moderate today. The primary pollutant identified is PM2.5 (fine particles).
Measurements from five valid monitoring points show a PM2.5 concentration of 15.02485 µg/m³ and a PM10 level of 15.9334 µg/m³. These values are presented through OpenAQ data. 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
Harzgerode’s OpenAQ feed contains data from a single monitoring site that reports six pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). In total there are six rows of measurements, one for each pollutant, all originating from the Unterharz / Friedrichsbrunn location.
The timestamps show that five of the six pollutants were last updated on 2026-02-10 at 17:00 UTC, indicating very recent information for NO₂, O₃, PM10, PM2.5 and SO₂. The NO value is older, with its most recent record dated 2024-03-11 at 11:00 UTC, so the dataset mixes fresh and slightly outdated entries. Because each pollutant has only a single recorded value, the reported minimum, median and maximum are identical for every substance, meaning there is no observed spread in the data.
Specifically, the current readings are 0.711355 µg/m³ for NO, 7.17459 µg/m³ for NO₂, 48.8765 µg/m³ for O₃, 15.9334 µg/m³ for PM10, 15.02485 µg/m³ for PM2.5 and 2.019115 µg/m³ for SO₂. The uniformity of these numbers reflects that the dataset captures a single snapshot rather than a range of values over time. Consequently, while the recent timestamps give confidence in the timeliness of most pollutants, the limited number of stations and lack of variability mean that conditions can differ across other parts of Harzgerode or at other times not represented here.

Data notes
The data shown for Harzgerode is based on five valid measurements and was refreshed within three days, with the latest update recorded at 2026‑02‑10 17:00 UTC. These values represent a snapshot of current conditions; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
