Ecosystems | NASA Earthdata
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through …
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.

Checking Earth's Vital Signs | NASA Earthdata
2020年7月21日 · Both are endangered, due in large part to habitat fragmentation from logging and other human activities. And both are evidence of the Earth's dwindling natural resources, according to the Millennium Ecosystem Assessment (MA), the first-ever global effort to take stock of the planet's ecosystem health. And the vital signs aren't looking good.

2021年4月13日 · The EPI provides quantitative metrics for evaluating a country’s environmental performance in different policy categories relative to clearly defined targets, and aggregates data on many indicators of sustainability into a single number – the EPI Score, which ranges from 0 …
Grasping the Subtle Needs of Vegetation | NASA Earthdata
2020年12月28日 · 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.
Scorecard on the Environment - Earthdata
The 2008 EPI ranks countries based on two objectives. “Environmental health” assesses environmental conditions that directly affect human health: air quality, sanitation, and safe drinking water. “Ecosystem vitality” measures how well a country protects its natural resources and maintains healthy ecosystems.
Invasion of the Ctenophores | NASA Earthdata
2020年12月28日 · There is little interest in monitoring the species unless it has a major effect on people or the ecosystem, and by then the damage is done. Knowing where the ctenophore is likely to spread could mean that countries might impose rules on ships for filtering their ballast waters, to avoid introducing the species in a place it would likely thrive.
