Air quality today
The air quality in Héming today is classified as Good. The primary pollutant identified is PM10, which represents the coarser fraction of particulate matter measured in the city’s monitoring network.
Three valid measurements were recorded, with a reference value for PM10 set at 3.3 µg/m³. 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 Héming includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All of these come from a single monitoring location, so the city’s air‑quality picture is based on one row per pollutant. The NO reading is 4.2 µg/m³ recorded at Heming on 2024-03-11 08:00 UTC, while the more recent updates for NO₂ (3.5 µg/m³), PM₁₀ (3.3 µg/m³) and SO₂ (0.2 µg/m³) were all logged on 2026-02-10 15:00 UTC. Because each pollutant has only one value, the minimum, median and maximum are identical, giving a perfectly flat statistical spread for every compound.
The freshness of the data varies across the set. The NO measurement is over two years old, whereas the other three pollutants have been refreshed within the last few days, indicating that most of the current snapshot relies on very recent observations for NO₂, PM₁₀ and SO₂ but older information for NO. With only one monitoring station contributing, there is no spatial coverage to capture variations across different neighbourhoods in Héming; conditions can differ elsewhere in the city or change throughout the day.
In practical terms, users should note that the available numbers represent a single point in time and space. The dataset provides a concise view of four key gases, but the limited number of rows and the age disparity for NO mean it cannot describe broader temporal trends or location‑specific differences within Héming.

Data notes
The current dataset for Héming includes three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC, meaning it is updated within three days. These values represent a snapshot of ambient conditions captured by the monitoring network; actual air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
