Mar 20, 2025 · 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.

Feb 5, 2024 · 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 ...

Dec 22, 2020 · Building upon this research, Dr. Dietze is part of a team working on an approach integrating remotely-sensed data with model data that will enable terrestrial ecosystem models to predict reflectance spectra. Reflectance spectra are a measure of the wavelengths of light that are returned rather than absorbed by a plant or other object.

Dec 28, 2020 · 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.

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.

Jul 28, 2020 · 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 ...

Dec 31, 2000 · The Millennium Ecosystem Assessment: MA Climate and Land Cover provides data and information on global gridded climatological variables, global land cover maps, and national and international protected areas.

Feb 15, 2025 · NASA biosphere data are critical for understanding Earth's species, climate regulation and change, and its ecosystem processes.

Feb 2, 2025 · 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.
