In fall 2025, more than 50 educators and over 1,500 young people across Maine and New Hampshire participated in NASA’s Global Learning and Observation to Benefit the Environment (GLOBE) Green Down, a citizen science (also known as participatory science or community science) initiative that engages students and volunteers in tracking seasonal changes in plant life. By observing and documenting leaf color change and leaf drop, participants contributed valuable data used by scientists studying how ecosystems respond to a changing climate.
