Brian Campbell, ICESat-2 education lead and science liaison and outreach lead for the NASA GLOBE Observer Trees Tool, and his son Andy, demonstrate how to make and use a simple paper clinometer to measure the height of trees. To do this activity, you will need a printout of the clinometer activity sheet, a straw, a pen or pencil, scissors, tape, string, and some sort of weight for the string such as a washer, nut or paperclip. A rigid surface such as clipboard or piece of cardboard may also be needed to attach the clinometer to as you are measuring the angle to the top of the tree.
One of the major ways students can perform student research is to compare GLOBE student and citizen science tree height data to height data from the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2). By comparing this data, students can see just how close the satellite tracks over their locations and if certain GLOBE-measured trees have been measured by ICESat-2. Amy FitzGerrell, from the National Snow and Ice Data Center (NSIDC) in Colorado, guided us with an interactive tutorial of the Open Altimetry online tool.

Valerie Casasanto, outreach manager for the Ice, Cloud, and land Elevation Satellite-2, or ICESat-2, demonstrates the "Motion in the Ocean" water density activity. The materials needed are tennis ball tubes, a tub or container for excess water, salt, food coloring, tubing or a clear straw (a disassembled pen body could also work), and high density foam (such as from a children's puzzle floor mat) to make the fluid separator plugs
Brian Campbell, of the NASA ICESat-2 Team, highlights the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and its use of lasers to measure the height of Earth’s objects, like ice and trees duing this Facebook Live event as part of the Center for Science & Industry's (COSI) Virtual Science Festival in May 2020. There is also an interactive discussion on how to use the Open Altimetry online tool to view ICESat-2 tree height and tree canopy data across the globe.

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).
