Posted by & filed under news.

From 1 September to 15 October many citizens in 11 European cities have taken pictures of their blue sky with iSPEX to contribute to our campaign. In total 5386 measurements have been made in this period. An animation of the preliminary results of all measurements is shown below. Many thanks you to all of you who have contributed!

Over the next weeks we will process all gathered. Stay tuned for the results.
