As part of the Trees Around the GLOBE Student Research Campaign and the NASA GLOBE Observer App Trees Tool for Citizen Science, tree height is a major observation that aligns to much of what NASA satellite missions and instruments are doing from space. Students, educators, and citizen scientists can take ground-based observations of tree heights using a hand-held clinometer or the NASA GLOBE Observer App for citizen science. By taking multiple observations of tree heights from the ground and do comparisons to tree height information from the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and the Global Ecosystem Dynamics Investigation (GEDI) on the International Space Station. The session will highlight how global student, educator and citizen scientist participants, of the Trees Around the GLOBE Student Research Campaign, can compare the ground-based tree height data with that of the missions, using online tools like Open Altimetry, designed by the National Snow and Ice Data Center (NSIDC). A demonstration of how the NASA GLOBE Observer App's Tree Tool works to measure the height of trees, from the ground. As each tree is geolocated (time-tagged) with a specific latitude and longitude, on the ground using the NASA GLOBE Observer Trees Tool and from space from ICESat-2 and GEDI, the tree height comparisons can represent several levels of comparative data.
