Air quality today

The air quality in Hart today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 4.66 µg/m³ based on five valid observations recorded by OpenAQ.

Overall, the conditions meet the criteria for a Good rating with no additional pollutants highlighted. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Hart air‑quality record draws on a single monitoring site – Elvetham Heath – which contributed five separate data rows covering the full set of measured pollutants. Those pollutants are PM1, reported in micrograms per cubic metre; PM2.5, also in µg/m³; relative humidity as a percentage; temperature in degrees Celsius; and UM003, expressed as particles per cubic centimetre.

All five observations were last updated on 2026‑02‑10 at 21:00 UTC, meaning the freshest data for every pollutant is less than a week old. For PM1 the single value recorded is 1.6079999983310698 µg/m³; PM2.5 shows 4.655833339691162 µg/m³. Relative humidity stands at 64.97416648864747 %, while temperature was measured at 13.936500040690104 °C. The UM003 count is 318.38616638183595 particles/cm³. Because each pollutant has only one recorded point, the minimum, median and maximum are identical, giving no spread to describe variability.

The dataset therefore offers a very narrow snapshot: coverage is limited to one location and five rows, with all values captured at the same moment. While this provides an up‑to‑date picture of conditions at Elvetham Heath, it does not reflect spatial differences across Hart or changes over time. Users should keep in mind that air quality can differ elsewhere in the city and that additional monitoring would be needed to capture a broader range of conditions.

Data notes

The data shown for Hart reflects five valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T21:00:00+00:00. These figures provide a current snapshot of air quality across the city, but conditions can differ by neighbourhood and change throughout the day, so local variations may not be captured in this summary.
