This video shows how students, teachers, and citizen scientists can take existing GLOBE Observer data for tree height and compare it to the tree canopy height data from the NASA Ice, Cloud, and land Elevation Satellite- or ICESat-2 Mission. The online Open Altimetry Tool allows you to look and see when ICESat-2 flew over or near the location of the tree you have the GLOBE data for already. It is a fun and simple thing to do and helps you become a part of a larger NASA mission.
NASA's ICESat-2 uses lasers to measure heights on Earth, including tree heights. Join NASA Wallop's Brian Campbell, ICESat-2 Education Lead (and NASA GLOBE Observer Trees Science Lead) as he demos all about the satellite. Plus, learn how to look at the data coming from ICESat-2 on the Open Altimetry online tool.
We live, play and work with trees everywhere around the globe. The Trees Around the GLOBE Student Research Campaign commenced on September 15, 2018 in conjunction with NASA's ICESat-2 satellite launch on the same date at 6:02am PDT. The ICESat-2 satellite uses an on-board laser altimeter system to measure the height of Earth. Measurements of ice sheets, sea ice, trees, bodies of water, mountains are all part of what ICESat-2 measures. The Trees Around the GLOBE Student Research Campaign is a GLOBE Program campaign focusing on tree height - one of the measurements conducted by the ICESat-2 mission.
This is a video archive of the GLOBE Observer: Trees Snapchat story that went out on the NASA Snapchat account on March 26, 2019 as part of the release of the new Trees tool.
The Trees Tool in the NASA GLOBE Observer (NASA GO) app allows citizen scientist observers to use their mobile devices to take tree height and tree circumference measurements all over the globe.
#PhotonPhriday looks at how ICESat-2 measures Earth – from Antarctic dunes to the Bahamas to Greenland’s glaciers.
The National Snow and Ice Data Center (NSIDC) archives and distributes data from ICESat-2. Here is their intro video to the mission.
The Trees Around the GLOBE Student Research Campaign is a multi-year campaign for students and educators from around the world. This campaign highlights measurements of tree height and focuses on the scientific, cultural, and personal foundation of trees. Learn more about the campaign here.
ICESat-2 is an incredibly precise space laser that features the latest in NASA technology To measure ice heights, engineers have to take ICESat-2’s instrument ATLAS to the extreme – sometimes going big, sometimes going small, but always keeping it precise.

If ICESat-2 flew over a football field, it would take measurements within each yard line (green circles) – plus there's six of these green laser beams taking measurements at once! The first ICESat instrument only fired 40 times a second, and would have taken a measurement in each end zone (red circles).
NASA cryospheric scientist Kelly Brunt and ICESat-2 Deputy Project Scientist Tom Neumann recall some of the highlights and challenges from the recent 88-South Antarctic Traverse.
