Results from the GLOBE Eclipse Challenge: Clouds and Our Solar-Powered Earth

Between 15 March and 15 April, volunteers from over 90 countries collected more than 23,000 GLOBE Clouds observations, generating 25,444 satellite matches. Volunteers in the United States submitted 13,900+ cloud observations, making it the most active country in the challenge. Saudi Arabia, Croatia, Israel, Mexico, and Thailand were the next most active countries. Some volunteers also took observations aboard ships!

The challenge focused on documenting changing cloud conditions at different times of the day, from day to day and during an eclipse. This challenge also provides a longer-term comparison data set to the observations submitted during the 2018 Spring Clouds Challenge, which also took place from 15 March to 15 April. This matching time frame will allow scientists and others (such as students) to examine change across years. Data from both challenges are available on the GLOBE Observer clouds data page.

During the challenge, the GLOBE Observer team produced a series of short videos in both English and Spanish that highlighted cloud science and data collection. You can view them by clicking the links on this page.

Don't forget, if you participated in the challenge, you can download a certificate in English or Spanish on the Eclipse Challenge page. The pdf certificate is formatted so that you can add your name after you download the file.

Even though the challenge is over, we encourage you to continue to share your cloud observations with GLOBE. Each observation you contribute builds the decades-long GLOBE database, providing a long-term record of cloud conditions. You can also earn badges and create a streak as you continue to observe. Thank you for volunteering with GLOBE!
