2024年2月5日 · ORNL DAAC released a dataset of regional environmental and meteorological drivers from the PalEON Ecosystem Model Intercomparison Project , a coordinated effort to develop a set of terrestrial ecosystem model simulations with the ability to evaluate high-resolution ecophysiological causes and consequences of forest responses to climatic ...

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.

2025年2月14日 · The terrestrial hydrosphere includes water on the land surface and underground in the form of lakes, rivers, and groundwater along with total water storage. Trending Subtopics Sea Ice

2020年7月28日 · Biologists have divided the terrestrial portions of the Earth into biomes, regions characterized by specific climatic conditions and by certain types of life, especially vegetation. For each biome, as defined by the World Wildlife Fund - U.S. Conservation Science Program, Sanderson and his collaborators mapped the original scores to a new scale ...

2020年12月28日 · Wilson used data from these eleven towers to calculate the normalized difference vegetation index (NDVI) and Leaf Area Index (LAI), indicators of overall plant health, seasonal growth, and changes in the amount of leaf and vegetation cover in the ecosystem surrounding the tower. “NDVI and LAI data can reveal an ecosystem’s role,” Wilson said.

Data collected by NASA’s Earth-observing instruments provide information on the terrestrial hydrosphere including watershed extent, water quality, changes in surface and groundwater, and water surface elevation. In addition, NASA hydrospheric model data provide information on runoff and evapotranspiration.

The extent and seasonal, interannual, and decadal variation of inundated wetland area play key roles in ecosystem dynamics. Wetlands contribute approximately one fourth of the total methane annually emitted to the atmosphere and are identified as the primary contributor to interannual variations in the growth rate of atmospheric methane ...

2020年12月28日 · Wetlands are places where land is permanently or seasonally saturated with water, forming a distinct ecosystem that is both aquatic and land-based. Although wetlands may exist wherever water collects, they often border rivers and lakes, creating spongy coastlines astir with fish, birds, and the drone of mosquitoes and dragonflies.

2022年3月9日 · MAAP is designed to provide the aboveground terrestrial carbon research community with airborne and space-based data that provides improved geographic coverage at better spatial resolutions by bringing together data from NASA’s Global Ecosystem Dynamics Investigation (GEDI) lidar mission, the NASA-ISRO Synthetic Aperture Radar (NISAR) mission ...
