Trees Challenge 2022 Summary and Wrap-up
From 11 October to 11 November 2022, we asked our volunteer scientists to help us estimate the number of trees in the areas around them and contribute to tree and climate science by sharing their observations of trees. The response was impressive! We received over 4700 observations from more than 750 individual participants! Read more in the challenge summary.  >>

GLOBE Observer Trees App Used in Documenting a Critically Endangered Species
The Araucária is an ancient tree whose ancestors populated the landscape before even the dinosaurs, more than 240 million years ago! Although once dominating the entirety of the Atlantic Forest, the Araucária is now an endangered species that occupies only 2% of its historic range.  >>

GLOBE Goes to the Amazon
This is Rusty Low, scientist with the GLOBE Observer Science Team, reporting from the Amazon Rainforest in the Tapajós National Forest, Municipality of Belterra, Para, Brazil for the NASA GLOBE Trees Challenge 2022: Trees in a Changing Climate. My co-author for this blog is Erick Luiz Souza Silva. He is a graduate student at the Federal University of Brasilia.  >>

Comparing GLOBE Trees to ICESat-2: A New Scientific Publication
Can your tree measurements give scientists assessing tree heights with satellite data a useful ground-based reference point? According to a new analysis of GLOBE Observer tree data, it can in certain circumstances. There are four things you can do to make sure your observations are useful.  >>

What do trees, tree height, lasers, and a NASA satellite called the Ice, Cloud, and land Elevation Satellite-2 have in common?  >>

Results from the Spring 2022 Tree Height and Land Cover Intensive Observation Period
The Trees Around the GLOBE Student Research Campaign hosted the Spring 2022 Tree Height and Land Cover Intensive Observation Period (IOP) from 22 April though 22 May 2022.  >>

GLOBE Student Interns Recognized for AGU Scientific Presentations
Two GLOBE students were recently recognized by the American Geophysical Union (AGU) with an Outstanding Student Award for work presented at the Fall AGU Meeting.  >>

Tree Height, Clouds, and ICESat-2: An Example of the Importance of Taking Multiple Observations at the Same Time and Same Place
Taking multiple GLOBE Program observations using the NASA GLOBE Observer – NASA GO – app’s tools (i.e. clouds, mosquito habitats, land cover, and tree height) in the same location at the same time helps students, citizen sciences, and professional researchers better understand what is happening in an environment.  >>

Information about The GLOBE Program was included as part of the NASA presence at the recent 26th United Nations Climate Change Conference of the Parties (COP26) in Glasgow, Scotland.  >>

3 Years of ICESat-2 and NASA GLOBE Observer Tree Heights
Three years ago, on September 15, 2018, at 6:02 a.m. PDT, NASA launched the Ice, Cloud, and land Elevation Satellite-2 or ICESat-2 from the Vandenberg Air Force Base (now the Vandenberg Space Force Base) in Lompoc, California.  >>
