    GLOBE Observer invites people to make environmental observations that complement NASA satellite observations to help scientists studying Earth and the global environment. Those in the 120+ GLOBE countries can download and use the app.

    By using the GLOBE Observer app, you are joining the GLOBE community and contributing important scientific data to NASA and GLOBE, your local community, and students and scientists worldwide.

    To participate, download the app, register with an email address (you can also register using a web form), then go outside and follow the prompts in the app to observe your environment.

    New and interested users are encouraged to learn more about the GLOBE Program. A one-page summary of GLOBE Observer is also available.

    Clouds Apps. By photographing clouds, recording sky observations, and comparing them with NASA satellite data, you can help scientists gain a new perspective on clouds that satellites just can’t provide: from the ground looking up! This new perspective will help refine satellite-derived models and enhance scientific understanding of Earth’s atmosphere.
