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.

Earth's cryosphere includes all its frozen structures, such as sea ice, ice caps, and permafrost. Understanding changes in the cryosphere provides scientists with valuable information about the past, present, and future of the planet. ICESat-2 will help scientists learn more about Earth's ice.

What is ice? NASA and ICESat-2 scientists explain the unique and essential qualities of frozen water. Water, unlike other types of matter, is less dense as a solid than as a liquid, allowing ice cubes -- as well as bigger chunks of ice -- to float on top of liquid water. Floating ice on lakes and oceans is important, allowing life to live in the water beneath it. Ice covered regions also have a big impact on our planet's climate and weather, even far away from the polar regions.
