            "description": "Music: \"Overview Effect,\" \"All In Stride,\" Universal Production Music. NASA utilizes advanced satellite lidar technology to better understand and observe Earth’s forests—crucial ecosystems that absorb roughly 30 percent of atmospheric carbon. Remote sensing scientist, Laura Duncanson, explains the challenge of studying vast, remote regions where traditional field research is limited. For over 50 years, satellites like Landsat have tracked forest cover, but have lacked the ability to measure how much carbon these forests contain. That’s where NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission comes in. GEDI provides high-resolution 3D data on tree canopy height, canopy structure, and surface elevation, allowing scientists to determine forest biomass. However, based on GEDI’s orbit on the International Space Station (ISS), it is unable to capture data near Earth’s poles. To fill that gap, NASA uses the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2), which, although not originally designed for forests, provides complementary 3D forest data, especially in boreal regions. Together, the two lidar systems enable the first comprehensive global biomass map, revealing where and how much carbon is being lost or regained in forests. With this new understanding comes smarter conservation and restoration efforts, assisting in identifying carbon-rich areas to prioritize protection. With these NASA Earth science missions, we can see a clearer global picture of our planet and its carbon balance.

            "description": "This visualization depicts how ICESat-2 data is being used to study vegetation canopy. The visualization begins with a view of 6 beams passing over forested mountains, before zooming in on a single beam and introducing the data classification scheme.  Data points are classified as ground (light brown), vegetation (green), vegetation canopy (tan), or unclassified (grey).  A transparent scale using meters for distance and altitude is overlaid momentarily before the camera moves on and explores the rest of the beam data. Altitude is exaggerated 5x. || ICESat-2_vegetation_canopy.03680_print.jpg (1024x576) [106.5 KB] || ICESat-2_vegetation_canopy.03680_searchweb.png (320x180) [47.1 KB] || ICESat-2_vegetation_canopy.03680_thm.png (80x40) [4.0 KB] || ICESat-2_vegetation_canopy_1080p60.webm (1920x1080) [31.0 MB] || icesat2_vegetation_canopy (3840x2160) [1.0 MB] || ICESat-2_vegetation_canopy_1080p60.mp4 (1920x1080) [134.2 MB] || ",
