North America Phenology Campaign - North America
North American Phenology Campaign
HOw to partIcipate
This fall there are two ways to participate!
- Monitor leaves on an individual tree using GLOBE’s Green-Down protocol.
- Take landscape photos for NASA’s PACE satellite mission using GLOBE’s Land Cover tool in the GLOBE Observer app. Volunteer observations will help verify PACE vegetation color indices.
Learn more at our webinar on Wednesday, August 19, at 3 p.m. ET
Join us at a webinar to learn about the North American Green-Down Campaign to monitor fall color change with the NASA-sponsored GLOBE Program. In this webinar you will learn how to support your audience as they monitor tree fall color change at your site and share data with a global network. We will share tips and resources for making this successful with your audience, and all attendees will be able to request a free green-down citizen science kit!
You will also hear from NASA’s PACE terrestrial scientists, who are interested in comparing your ground-based photos of fall leaf color changes to PACE data.

Monitor leaves on an individual tree
Gather your materials
- Find data sheets and the field guide on the Green-Down protocol page.
- Print a GLOBE Plant Color Guide or use the built in guide in the GLOBE Observer app.
Collect your data
Measure leaf color change or growth twice a week by following the four quick steps on the Tutorials page or read the Green-Down or Green-Up Protocol for details.
Enter your data
Use the GLOBE Observer app or paper data sheets and Desktop Data Entry to share your data to the public database.
Take Landscape photos for nasa's pace mission
Volunteer observations will help verify PACE vegetation color indices to support the refinement of a novel data product. Learn more about how PACE is tracking leaf color change in this video: "Leaf Peeping with PACE" (1:25 minutes)
Gather your materials
- Download the GLOBE Observer app.
Collect and Enter your data
Choose a location where you can see the forest landscape. Use the Land Cover tool in the GLOBE Observer App to take photos in each cardinal direction, up, down, and also take a "Feature Photo" of the landscape.
Leaf color changes rapidly and regular repeat observations are appreciated!
Resources
Formal Educators: Green-Down Sequence
Navigate the phenology campaign using a sequence of six short activities to guide you through the fall. The guides include age-appropriate activities and data sheets.
- K-8 Educators GLOBE Green-Down Sequence (for grades K-8, ages 5 -13)
- 9-12 Educators GLOBE Green-Down Sequence (for grades 9-12, ages 14 -18)
Informal Educators and Facilitators: Green-Down Toolkit
The Green-Down Toolkit has information for faciltiating green-down with your local audience. It includes instructions, the data sheet and field guide, pre-made flyer and social media posts, and literacy and art connections.
