Air quality today
The air quality in Harich today is classified as Good. The primary pollutant identified is PM10, which refers to coarser particulate matter.
Four valid measurements were recorded, showing a PM10 reference value of 15.95. This indicates that the current concentration aligns with the Good category 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 air‑quality record for Harich in Frisia currently draws on a single monitoring location, Balk‑Trophornsterweg, which supplies four rows of data – one for each measured pollutant. The dataset therefore includes nitrogen monoxide (NO) at 0.56 µg/m³, nitrogen dioxide (NO₂) at 18.42 µg/m³, ozone (O₃) at 7.69 µg/m³ and particulate matter up to 10 µm (PM10) at 15.95 µg/m³. All four entries share the same timestamp, last updated on 2026‑02‑10 21:00 UTC, and are flagged as having been refreshed within the past seven days.
Because each pollutant is represented by a single row, the statistical spread is effectively zero – the minimum, median and maximum values are identical for every compound. This uniformity means there is no observed variability in the reported concentrations across the limited sample set. The data therefore describe a snapshot rather than a range of conditions, and any day‑to‑day or location‑to‑location differences within Harich cannot be captured from this source alone.
With only one sensor contributing to the record, coverage across the city is narrow; broader spatial patterns are not reflected in the current figures. Nonetheless, the timestamps indicate that the information is recent, so the values shown represent the latest conditions measured at Balk‑Trophornsterweg. Users should keep in mind that air quality can differ elsewhere in Harich and may change over time, so these numbers provide a point‑in‑time view rather than a comprehensive picture of the city’s atmosphere.

Data notes
The current dataset for Harich includes four valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 21:00 UTC; it is therefore considered updated within three days. While these figures give a reliable snapshot of overall conditions, air quality can differ across neighbourhoods and change throughout the day, so local variations may not be fully captured in this summary.
