- Global Ecosystem Dynamics Investigation 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
- Anthropogenic Human Influenced Ecosystems - NASA Earthdata
Our datasets useful to the study of human-influenced ecosystems include crop extent maps, urban air quality measurements, and land cover surveys These measurements and higher-order data products enable important studies into how humans shape Earth and how we can better care for ourselves and our home Get Human-Influenced Ecosystems Data
- Millennium Ecosystem Assessment: MA Biodiversity - Earthdata
The Millennium Ecosystem Assessment: MA Biodiversity provides data and information on amphibians, disease agents (extent and distribution of infectious and parasitic diseases), drylands (cattle, sheep and goats, and pasture), islands (fishing pressure, sewage pollution index and tourism), loss of natural land cover (biomes and realms), polar population, species distribution models, and
- Biome-BGC: Terrestrial Ecosystem Process Model, Version 4. 1. 1 | NASA . . .
Biome-BGC is a computer program that estimates fluxes and storage of energy, water, carbon, and nitrogen for the vegetation and soil components of terrestrial ecosystems The primary model purpose is to study global and regional interactions between climate, disturbance, and biogeochemical cycles Biome-BGC represents physical and biological processes that control fluxes of energy and mass
- Terrestrial Ecosystems - NASA Earthdata
NASA's terrestrial ecosystem data give researchers the ability explore the creature and plant communities living on land virtually anywhere on Earth
- PnET-BGC: Modeling Biogeochemical Processes in a Northern . . . - Earthdata
This archived model product contains the directions, executables, and procedures for running PnET-BGC to recreate the results of Gbondo-Tugbawa, S S , C T Driscoll , J D Aber and G E Likens 2001 The evaluation of an integrated biogeochemical model (PnET-BGC) at a northern hardwood forest ecosystem Water Resources Research 37:1057-1070 Gbondo-Tugbawa et al, 2001 Excerptfrom Abstract: An
- Global Ecosystem Dynamics Investigation | NASA Earthdata
NASA's Global Ecosystem Dynamics Investigation (GEDI) project focuses on how deforestation has contributed to atmospheric CO2 concentrations, how much carbon forests will absorb in the future, and how habitat degradation will affect global variability of life
- CENTURY: Modeling Ecosystem Responses to Climate Change, Version 4 . . .
Description The CENTURY model, Version 4, is a general model of plant-soil nutrient cycling that is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas CENTURY is composed of a soil organic matter decomposition submodel, a water budget model, a grassland crop submodel, a forest production
