You can (voluntarily) submit your Dark Sky Meter readings. Besides the map on this website, the data you provide will be sent to scientists worldwide. Of course, no personal data is collected. Just location, weather and darkness information.
One of the most famous campaigns is called Globe at Night, you probably know it.
They did research on our app and it proved to be very reliable in regression tests along with other devices.
And we are really proud that DSM (that is you!) is providing the majority of measurements (2791)!
Here’s a great infographic.
Also check out the beautiful Globe at Night website. We will join forces during the 2015 year of light!
