Whether you are at school, at home or self-isolating you can be a part of the United Nations International Day of Clean Air for Blue Skies on Monday 7 September. How? By contributing to NASA’s citizen science global database!

Download the GLOBE Observer app and photograph the cloud cover from your window, balcony, garden or wherever you are. An email address is all that’s required, and the app will guide you through the process – including helping you identify the cloud type you’re observing.

Make your observation when one of NASA’s satellites is passing overhead using the app’s satellite alert and you will receive a verification email from the GLOBE Clouds team at NASA’s Langley Research Centre.

Don’t worry, if you can’t make your observations on 7 September, the GLOBE Clouds team would still like your cloud photos and data, just take them on a different day.
