Measure Air Pollution in Athens with your smartphone!

The iSPEX project actively involves citizens in the scientific measurement of air pollution. With the iSPEX add-on you can transform your smartphone into an optical sensor that is suited to measure tiny atmospheric particles, also called aerosols. Atmospheric aerosols play an important but as-yet poorly understood role in climate and air quality, with significant impacts on our environment, health, and air traffic.

Athens is one of the cities that participate in the iSPEX-EU 2015. IAASARS/NOA welcomes you to join its local campaign and measure Athens skies from 1 September to 30 October! IAASARS/NOA is leading the local campaign activities, working closely with the iSPEX team at Leiden University in the Netherlands. The iSPEX-EU local campaign is closely interlinked with activities of the Building a Centre of Excellence for Earth Observation based monitoring of Natural Disasters in south-eastern Europe (BEYOND).
