MARCH EVENT CANCELLED - STAY TUNED FOR DETAILS ABOUT OUR APRIL EVENT! Join us for GLOBE Observer Connect, a new series of short conversations about GLOBE data, science, and the latest updates. For our first conversation, Peder Nelson, science lead for the Land Cover tool and a researcher in the College of Earth, Ocean and Atmospheric Sciences at Oregon State University, will talk about the surface conditions information we collect in the app, especially snow cover, and how that data can be applied to a wide range of research topics. After his brief presentation, there will be a chance for a discussion and questions.  >>

Learn about the data collected by the Global Ecosystem Dynamics Investigation, or GEDI, and how it measures the 3D structure of Earth from the International Space Station using near-infrared lasers. The data that GEDI collects are immensely valuable for improving our understanding of the world's forests and complex carbon cycles.  >>

This webinar for the Trees Around the GLOBE Student Research Campaign will focus on country comparisons of land cover and tree heights using online data mapping tools that the campaign has highlighted often. Peder Nelson (Oregon State University) will present on, and lead a discussion thinking about, the growth rate of trees over time with the context of "Does your city/town have a tree plan?"  >>

The Global Learning and Observations to Benefit the Environment Program invites you to take part in our upcoming Trees Challenge: “Trees in a Changing Climate,” and contribute data toward a better understanding of trees and forests.  >>

The Trees Around the GLOBE Student Research Campaign, GLOBE European Phenology Campaign, UNEP/GRID-Warsaw Centre (coordinator of GLOBE Poland), and the Urban Heat Island Effect - Surface Temperature Field Program, would like to invite you to participate in the Spring 2022 GLOBE Tree Height and Land Cover Intensive Observation Period (IOP) from 22 April through 22 May 2022.  >>

Join GLOBE for the 2021 Community Trees Challenge while we learn about trees and advance our understanding of Earth’s forests together.  >>

To celebrate the 50th anniversary of Earth Day and the 25th anniversary of the GLOBE Program, 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. The individuals, schools, and registered teams that measure the most trees will be recognized as top observers in the challenge. Learn more on the challenge webpage.  >>

For our education partners interested in incorporating the Trees 2020 Challenge: Make Every Tree Count into their Earth Day planning, we are offering an informational webinar on February 19th at 2:00 pm EST/19:00 UTC. This webinar (an hour and a half long) will introduce a package of resources to support informal educators and GLOBE schools. The package includes information about trees and NASA science, connections to local tree science relevant to your community, ideas about how to manage a Trees challenge, learning activities, and other resources. The webinar will be recorded and provided for reference on the challenge website, https://observer.globe.gov/trees-2020.  >>
