Live Data

This website is designed as a central platform for air pollution research and monitoring in the Hampshire region, bringing together data from multiple air quality sensor networks, including PurpleAir, Airly, EarthSense, and the DEFRA network. It also features annual mean pollutant data from the DEFRA UK Air, with the option to download the data. The aim of this page is to serve as a collective space for accessing, viewing, and exploring air quality data from a range of sources. The intended audience at this stage includes researchers in air pollution and policy decision-makers.
