The NASA Moon Trees Quest asked a great deal from our GLOBE Observers around the States, and observers delivered: during the quest, there were 90 individual Apollo 14 Moon Trees and Moon Tree species identified, measured, and documented in the GLOBE database.  >>

The GLOBE Program had a strong presence at the American Geophysical Union Fall Meeting, held from 11 December to 15 December in San Francisco, California, USA. Nearly thirty posters or presentations referenced GLOBE, including some student posters that will be presented virtually in January.  >>

Over the last five years, observations of tree height have become a major observation within The GLOBE Program. This is primarily due to several things: The launch of the NASA Ice, Cloud, and land Elevation Satellite-2 or ICESat-2, the start of the Trees Around the GLOBE Student Research Campaign, the release of The GLOBE Program’s GLOBE Observer Trees tool, and the ability to compare ground-based tree height observations, from GLOBE, to space-based observations of Earth’s tree heights from the NASA Ice, Cloud and land Elevation Satellite-2 or ICESat-2. In this blog, we will explore these various programs and methods of measuring and making sense of tree height observations through historical information, observations, and data metrics over the last five years.  >>

Building off of Amos et al. (2020)’s work, NASA intern Jessica Mo helped generate and implement quality checks for data submitted through GLOBE Observer’s citizen science protocols. Read on to learn what Jessica discovered through her analysis.  >>

The GLOBE Annual Meeting took place in Denver, Colorado, USA from 17-20 July, and showcased a variety of topics and presentations by GLOBE community members and keynote speakers.  >>

It was on January 31, 1971, when NASA launched the Apollo 14 spacecraft. Decades later, on December 11, 2022, the Orion Capsule successfully splashed down in the Pacific Ocean. But did you know that there were hundreds of tree seeds onboard both missions?  >>

A look back at the Trees Challenge from 2022, as well as what an active observation group in Pennsylvania has been up to related to measuring trees.  >>

From 12-16 December 2022, The GLOBE Program and members of the GLOBE community attended the American Geophysical Union’s Fall Meeting in Chicago, Illinois, an annual gathering of Earth scientists from around the world sharing their research and discoveries.  >>

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.  >>
