iSPEX-EU: A European-wide Citizen Science Campaign for the Measurement of Aerosols with Smartphones
As part of the LIGHT2015 project, coordinated by the European Physical Society, Leiden Observatory is organising a pilot European-wide Citizen Science campaign for the measurement of aerosols with iSPEX, a low-cost add-on and corresponding app for the iPhone. The campaign will run in over 10 major cities across Europe from 1-28 September 2015. With an anticipated 15,000 participants, this campaign therefore is a first step towards a worldwide network of citizen scientists who can provide air quality observations.
