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 Mid Sussex air‑quality dataset currently includes five measured pollutants – PM1, PM2.5, relative humidity, temperature and UM003 (particles per cubic centimetre). All of these values come from a single monitoring site at Bolney, so the data set consists of one row per pollutant. Each reading was last updated on 2026‑02‑10 03:00 UTC, which falls within the “updated within 7 days” freshness window, meaning the information is recent for all five parameters.
Because there is only one observation per pollutant, the reported statistics are identical across minimum, median and maximum values. PM1 registers at 3.8111666679382323 µg/m³, while PM2.5 measures 8.208333333333334 µg/m³. Relative humidity is recorded at 60.805333137512214 %, temperature at 13.364999945958454 °C and UM003 at 426.91649932861327 particles/cm³. The lack of variation (p10 equals p90) indicates that the dataset does not capture a range of conditions over time or across different locations within Mid Sussex.
Consequently, while the data are fresh, they represent a very limited snapshot from a single point source. This means city‑wide air quality can differ in other neighbourhoods or at other times, and the current figures should be understood as a narrow view rather than a comprehensive picture of Mid Sussex’s atmospheric conditions.

Data notes
The dataset for Mid Sussex contains five valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T03:00:00+00:00).
