Now in its third year, Cloud Appreciation Day is an internationally recognised day when people around the world are encouraged to spend a few moments with their heads in the clouds appreciating the beauty of the sky. Cloud Appreciation Day is on Friday September 13th, 2024, when anyone anywhere can take a photo of their sky and submit it for free to our Memory Cloud Atlas.

When adding their photo to the Atlas, contributors can also say how they feel about the sky that day. The Memory Cloud Atlas is open for contributions only on Cloud Appreciation Day itself. It will then remain as an online resource anyone can use to explore the skies of the world, alongside the 2023 Atlas Archive and the 2022 Atlas Archive. In this way, the Atlas serves as a yearly snapshot of a world looking up and a lasting document of how we all feel about the most dynamic, evocative, and universal of nature’s displays.
