GLOBE Observer Connect: Tracking Fall Color with PACE

22 September 2026, 1 pm ET (17:00 UTC)

GLOBE is working to provide you more opportunities to contribute to NASA science, including through the current North American Phenology Campaign. This fall, GLOBE volunteers are invited to use GLOBE Land Cover to document changing leaf colors to help verify a unique new PACE leaf color product.

Learn more about this opportunity to support PACE in a GLOBE Observer Connect conversation with PACE vegetation scientist, Skye Caplan, on 22 September 2026, at 1 pm ET (17:00 UTC). Skye will introduce PACE, a new hyperspectral satellite designed to measure plankton, aerosols, clouds, and the ocean ecosystem, and she will describe some of the ways she is using PACE data to study plants on land, including the new leaf color product.

After the GLOBE Observer Connect conversation, all are invited to stay on the webinar to learn more about the North American Phenology Campaign and the GLOBE Trees Around the GLOBE campaign.

YCC Webinar: GLOBE Green-Down in Alaska

Dr. Katie Spellman, of the GLOBE-Alaska partnership, shares about GLOBE green-down data for scenarios storytelling with youth. She will walk you through the process of using GLOBE data to imagine the future in a warmer climate, and then brainstorm and prioritize actions to create a better future, one that sustains the ecosystems we value and depend on. She will also share the results of her research documenting the effects of this scenarios storytelling approach on youth's sense of stewardship and science self-efficacy.
