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.
