Welcome

Welcome to GLOBE Observer, an international citizen science initiative to understand our global environment. Your observations help scientists track changes in clouds, water, plants, and other life in support of climate research. Scientists also use your data to verify NASA satellite data. And by submitting your observations, you can help students of all ages do real scientific research as part of the GLOBE Program. To participate, just download the app, go outside and follow the prompts in the app to observe your environment.

What You Can Do
Join the Community

You can become a GLOBE Observer. Just download the GLOBE Observer app and use it to observe the environment wherever you are. 

We will invite a few of the most active GLOBE Observers to join our volunteer leadership team for behind-the-scenes conversations with scientists, as well as community leadership opportunities. Interested in joining the leadership team? Contact us.
