Measuring aerosols with your smartphone

Today I participated in crowdsourced science: Measuring aerosols with my smartphone. Thousands of measurements in one day, all about the air quality in the Netherlands. The nice thing about this project is that laypeople are the researchers: everybody that ordered a free gadget for their iPhone is a researcher on this great sunny day. How the measurements work? See for yourself!

More on this project can be seen on their website This project was made possible with funds fron the Dutch lung foundation and the Academische Jaarprijs. So is it time to think of a big epi project in which crowd sourced data can be used?
