The next coming months, the data will be analyzed in full detail. After the analysis the measurements by the public will be compared to the aerosol-measurements by scientific equipment. Today, this equipment was set-up at the CESAR-research station at Cabauw, near Lopik. The primary goal of the iSPEX-experiment is to find out how accurate the massive the iSPEX-measurements are, and what kind of additional information about aerosols the measurements can provide. Snik: “Eventually the most important aspect of this project is that thousands of volunteers were able to perform scientific measurements themselves. We are convinced that this kind of citizen science, in which citizens help scientists with there research, has a great future ahead.”

To give all the holidaymakers (and all the students) a chance to also participate, a second national iSPEX-measure-day will be held in September, if the weather is good enough. That is why the participants are asked to keep their iSPEX-unit. Measurements in the meantime are welcome, so as soon as there is a day in the summer with a clear blue sky, people can perform measurements and send these through the App to the central database.

This unique science-project has been made possible because last year, iSPEX (a project by the University of Leiden, NOVA, SRON, KNMI and RIVM) won the Academische Jaarprijs, and thanks to the support of our partners Longfonds, CNG Net, Sanoma en Avantes. The members of the iSPEX-team all work in the development of the use of instrumentation and interpretation-models for researching the Earth, other planets in our solar system and planets orbiting other stars.
