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.
