Anthropogenic Human Influenced Ecosystems - NASA Earthdata Discover and Visualize Human Influenced Ecosystem Data NASA data help us understand Earth's changing systems in more detail than ever before, and visualizations bring these data to life, making Earth science concepts accessible, beautiful, and impactful
GEDI Lidar - NASA Earthdata The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation By accurately measuring forests in 3D, GEDI data play an important role in
Biodiversity Functions | NASA Earthdata The term "biodiversity" is used to describe the abundance and variety of life on Earth Having a diverse assemblage of plants, animals, and other organisms in a wide range of habitats promotes ecosystem productivity Thriving, diverse ecosystems help balance processes like nutrient storage and recycling, pollution filtration, and water resource maintenance In addition, diverse ecosystems trap
Wetlands | NASA Earthdata Wetlands are a type of terrain where the land is permanently or seasonally saturated with water Swamps and marshes are types of wetlands Insects, waterfowl, fish, amphibians, and other animals often find a home in wetlands, creating a complex ecosystem that combines land-based and aquatic life
ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station . . . Introduction This is the user guide for the ECOSTRESS Level-1 Radiance, Geolocation, and Map products The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission consists of a thermal infrared (TIR) multispectral scanner with five spectral bands operating between 8 and 12 5 μm The TIR data is acquired at a spatial resolution of approximately 35m x 70m with a
Invasion of the Ctenophores - NASA Earthdata And if it thrived, would it have the same disastrous effect on the ecosystem as it had in the Black Sea? Researchers used environmental data to build a model of potential habitats for the invasive ctenophore, Mnemiopsis leidyi The top image shows NASA Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) chlorophyll concentration in June
Biogeochemical Cycles - NASA Earthdata A Biogeochemical cycle is the movement of chemical elements from organism to physical environment to organism in more or less circular pathways
Grasping the Subtle Needs of Vegetation | NASA Earthdata These requirements are characterized by exchanges, or fluxes, between the ecosystem and the atmosphere If scientists can investigate the relationship between ecosystem health and the fluxes of carbon dioxide, water, and radiation, they can better understand global vegetation cycles and assess human impact in ecosystems around the world
A Rainforest Divided - NASA Earthdata Because the rainforest ecosystem supports complex webs of interactions, when extinction claims one animal, plant, or insect, other creatures suffer as well For instance, explained Laurance, a number of frog species use the little wallow ponds made by peccaries (wild pigs)
Biosphere | NASA Earthdata NASA biosphere data are critical for understanding Earth's species, climate regulation and change, and its ecosystem processes
