NASA Trees Challenge 2020: Make Every Tree Count celebrates Earth Day’s 50th anniversary, GLOBE Observer is hosting a month-long citizen science challenge in April 2020. Volunteers are invited to measure the height of as many different trees as possible throughout the month using the Trees tool in the GLOBE Observer app.


Let's promote the GLOBE Observer Citizen Science app on all our websites.
