What is GLOBE Observer?

  • A citizen science app allowing volunteers in GLOBE countries to take observations and contribute to the Global Learning and Observations to Benefit the Environment (GLOBE) community
  • A way to collect data to track changes in the environment in support of Earth system science research, and interpret NASA and other satellite data
  • An open data set available to scientists, and supporting students of all ages in doing real scientific research through the GLOBE Program

Download the app and follow the instructions to get started. Always follow guidelines from your local officials, and only participate in GLOBE activities or use the GLOBE Observer app if it is safe to do so.

What are GLOBE Observers up to?

In July 2022, the GLOBE Observer team planned a virtual event to celebrate GLOBE citizen science. The program was called GLOBE Observer Connection, Conversation, Celebration, or GO C3. Attendees heard from the science leads about how the GLOBE data is used and other programmatic updates, but the GLOBE volunteer panel discussion was a highlight of the event. Presented here is a segment of the video that introduced that conversation, the volunteers in their own words. Read more about GO C3, including the full recording, on the event page.
