North America Phenology Campaign

PACE Resources

NASA's PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite launched in 2024 and provides a unique hyperspectral view of the entire planet every 1–2 days. PACE gives us a novel look at timing and progression of fall colors across the landscape. 

NASA scientists working on the PACE satellite mission are asking for your help to collect forest landscape observations during the fall season using the GLOBE Observer Land Cover tool.

  • Explore what pigments exist in leaves. Appropriate for middle/secondary-aged youth and adults.

GLOBE Learning Activity: Global Patterns in Green-Up and Green-Down

  • Analyze visualizations and graphs that show the annual cycle of plant growth and decline. Appropriate for middle/secondary-aged youth and adults.

Elementary GLOBE All Year Long

  • Make observations during or across seasons, focusing on both a "big picture" view and a "zoomed-in" view. Appropriate for elementary-aged youth.
