            "title": "From Space to Soil: How NASA Sees Forests",
            "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.

NASA scientists studied the island's forests before and after the storm. Goddard's Lidar, Hyperspectral, and Thermal Imager (G-LiHT) is a portable instrument that maps forest health and structure from a small airplane resulting in detailed 3-D views of the forest. G-LiHT sends out 600,000 laser pulses every second mapping leaves and branches, rocks and streams. Almost 60% of the canopy trees lost branches, snapped in half, or were uprooted. Trees with wide, spreading crowns were reduced to a slender main trunk. Forests in Puerto Rico are now one-third shorter on average, after Hurricane Maria. The disturbances affected the whole ecosystem, from soils and streams to birds and frogs. G-LiHT data will help scientists understand how forests and wildlife respond to future changes. || SIGGRAPH_lidar_over_Puerto_Rico.01000_print.jpg (1024x576) [90.3 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_searchweb.png (320x180) [89.6 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_thm.png (80x40) [7.1 KB] || SIGGRAPH_PuertoRicoLidar.webm (1920x1080) [19.9 MB] || SIGGRAPH_lidar_over_Puerto_Rico.webm (1920x1080) [21.4 MB] || SIGGRAPH_PuertoRicoLidar.mp4 (1920x1080) [253.0 MB] || ",

By observing red, near-infrared, and green wavelengths of light reflected off the surface, it is possible to distinguish healthy vegetation (in green) from bare ground (in magenta).Music: Running by Dirk Ehlert [BMI], Guillermo De La Barreda [BMI]Watch this video on the NASA Goddard YouTube channel. || 12612-Mt-St-Helens-timelapse-print.jpg (1920x1080) [2.3 MB] || 12612-Mt-St-Helens-timelapse-print_searchweb.png (320x180) [129.3 KB] || 12612-Mt-St-Helens-timelapse-print_thm.png (80x40) [7.7 KB] || 12612-Mt-St-Helens-timelapse_prores.mov (1280x720) [1.3 GB] || 12612-Mt-St-Helens-timelapse_large.mp4 (1920x1080) [95.7 MB] || 12612-Mt-St-Helens-timelapse_youtube_hq.mov (1920x1080) [407.5 MB] || 12612-Mt-St-Helens-timelapse_appletv.m4v (1280x720) [44.8 MB] || 12612-Mt-St-Helens-timelapse_.webm (960x540) [38.8 MB] || GSFC_20170518_MtStHelens_m12612_Timelapse.en_US.vtt [42 bytes] || 12612-Mt-St-Helens-timelapse_ipod_sm.mp4 (320x240) [15.5 MB] || ",

            "description": "Twelve years of global deforestation, wildfires, windstorms, insect infestations, and more are captured in a new set of forest disturbance maps created from billions of pixels acquired by the imager on the NASA-USGS Landsat 7 satellite. The maps are the first to measure forest loss and gain using a consistent method around the globe at high spatial resolution, allowing scientists to compare forest changes in different countries and to monitor annual deforestation. Since each pixel in a Landsat image represents a piece of land about the size of a baseball diamond, researchers can see enough detail to tell local, regional and global stories. Hansen and colleagues analyzed 143 billion pixels in 654,000 Landsat images to compile maps of forest loss and gain between 2000 and 2012. During that period, 888,000 square miles (2.3 million square kilometers) of forest was lost, and 308,900 square miles (0.8 million square kilometers) regrew.

The computing required to generate these maps would have taken 15 years on a single desktop computer, but with cloud computing was performed in a few days.  Since 1972, the Landsat program has played a critical role in monitoring, understanding and managing the resources needed to sustain human life such as food, water and forests.

            "description": "A combination of lightning, drought and human activity caused fires to scorch more than one-third of Yellowstone National Park in the summer of 1988. Within a year, burn scars cast a sharp outline on the 793,880 acres affected by fire, distinguishing wide sections of recovering forest, meadows, grasslands and wetlands from unburned areas of the park. After more than two decades, satellite instruments can still detect these scars from space.In the time-lapse video below, a series of false-color images collected by USGS-NASA Landsat satellites from 1987 to 2018 show the burning and gradual regeneration of Yellowstone's forests following the 1988 fire season. Watch as burn scars (dark red) quickly replace large expanses of healthy green vegetation (dark green) by 1989. Notice how the scars slowly fade over time as new vegetation begins to grow and heal the landscape.Landsat Project Scientist Jeff Masek has been studying the recovery of the forest after the 1988 Yellowstone fires.  In the video below, he talks about how Landsat satellites detect the burn scars from space and distinguish them from healthy, un-burned forest and from new growth. || ",

            "description": "Earth's forests are of incalculable value; they are a vital component of the climate system - controlling gas, energy and water exchange between the surface and atmosphere; the tropical forests alone contain half of all biological species - diversity that underpins human and environmental wellbeing; they are a major source of revenue - timber, non-timber forest products and mineral reserves and they are the primary source of energy for over 2 billion people. Forests have never been under more pressure. Demand for their natural wealth and a hunger for land causes forest clearance at alarming rates. The UN Food and Agriculture Organization (FAO) estimates that the Earth loses an area about the size of a football field every 3 seconds - in the time it takes to make a sandwich an area equivalent to the National Mall in Washington, D.C., is cleared... somewhere on Earth trees are falling every second of every day. Based on a systematic sample of Landsat imagery at 4,016 locations around the tropical belt the European Commission's TREES 3 project is making estimates of forest cover change for the years 1990, 2000, 2005 and 2010 with new levels of precision. Preliminary results emphasize just how relentless the pressure on our planet is. Using archived and recent Landsat imagery we have measured dramatic changes to the African Continent for example. Since the 1970s natural vegetation (forests and savannas) have been converted to agricultural land at a tremendous pace. Around 50,000 sq. km per year are cleared - an area twice the size of Vermont. With the fastest growing population in the world such land cover conversions are unlikely to slow down any time soon, nor should the measuring programs. Landsat 8 and its European counterpart, Sentinel 2, are not being launched any sooner than they are needed.<!--             —>             <!—    —>  <!—  --> || ",

This timelapse of MODIS images shows the reduction of the forest from 2000-2010.Deforestation follows a fairly predictable pattern in these images. The first clearings that appear in the forest are in a fishbone pattern, arrayed along the edges of roads. Over time, the fishbones collapse into a mixture of forest remnants, cleared areas, and settlements. This pattern follows one of the most common deforestation trajectories in the Amazon. Legal and illegal roads penetrate a remote part of the forest, and small farmers migrate to the area. They claim land along the road and clear some of it for crops. Within a few years, heavy rains and erosion deplete the soil, and crop yields fall. Farmers then convert the degraded land to cattle pasture, and clear more forest for crops. Eventually the small land holders, having cleared much of their land, sell it or abandon it to large cattle holders, who consolidate the plots into large areas of pasture. || ",
