Air quality today

The air quality in East Hampshire today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 9.66 µg/m³ based on five valid readings reported through OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

East Hampshire’s air‑quality record is built from a single monitoring location in Alton, giving one row of data for each measured pollutant. The dataset therefore contains six distinct variables: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. Freshness varies across the series; five of the six measurements were last updated on 2026‑02‑10 at 21:00 UTC, while the PM10 value is older, recorded on 2025‑01‑13 at 23:00 UTC.

All pollutants show a single reported figure because only one observation exists for each. The median values are identical to the minimum and maximum, indicating no spread in the data set: PM1 registers 4.858 µg/m³, PM10 22.867 µg/m³, PM2.5 9.656 µg/m³, relative humidity 74.522 %, temperature 12.702 °C and UM003 1006.342 particles/cm³. Because there is no range of readings, the typical level for each pollutant is precisely the value listed.

The coverage is limited to one station, so spatial variation across East Hampshire cannot be captured. Moreover, the age of the PM10 reading—over a year old—means that recent conditions for coarse particulate matter are not reflected in the current snapshot, whereas the other five parameters are up‑to‑date within the last few days. Users should keep in mind that air quality can differ across neighborhoods and over time, and the present figures represent only the most recent single observation from Alton.

Data notes

The dataset for East Hampshire includes five valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T21:00:00+00:00). These figures represent a snapshot of current conditions; air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in this summary.
