About GLOBE at Night
The GLOBE at Night program is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and submit their observations to a website from a computer or smart phone. Light pollution threatens not only our “right to starlight”, but can affect energy consumption, wildlife and health. People in 115 countries contributed over 83,000 measurements during the campaigns each winter/spring over the last 7 years, making GLOBE at Night the most successful light pollution awareness campaign to date.
Check out the web application data submission process. The GLOBE at Night website is easy to use, comprehensive and holds an abundance of background information. The database is usable for comparisons with a variety of other databases, like how light pollution affects the foraging habits of bats.
