  • Anthropogenic Human Influenced Ecosystems | NASA Earthdata
    Data visualization is a powerful tool for analysis, trend and pattern recognition, and communication Our resources help you find world-class data visualizations to complement and enhance your research We also have tools and tutorials to help you translate human-influenced ecosystem data into compelling visuals
  • 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
  • Ecosystem Demography Model: U. S. Ecosystem Carbon Stocks . . . - Earthdata
    The Miami Land Use History Model (Miami-LU), a far simpler empirically-based ecosystem model, was used to track the history of disturbance, land use, fire, and ecosystem recovery The effects of fire suppression were also included
  • VEMAP 2: Annual Ecosystem Model Responses to U. S. Climate . . . - Earthdata
    The Vegetation-Ecosystem Modeling and Analysis Project (VEMAP) was a large, collaborative, multi-institutional, international effort whose goal was to evaluate the sensitivity of terrestrial ecosystem and vegetation processes to altered climate forcing and elevated atmospheric CO2
  • CMS: Modeled Net Ecosystem Exchange at 3-hourly Time Steps, 2004-2010
    This data set provides global, gridded, model-derived net ecosystem exchange (NEE) of CO2 flux between the land and atmosphere at 3-hourly time steps over seven years (2004-2010) at three different spatial resolutions: 0 5 x 0 5 degree, 2 0 x 2 5 degrees, and 4 0 x 5 0 degrees (latitude longitude)
  • CARVE: Ecosystem Scale CH4 Emission Derived from Aircraft . . . - Earthdata
    This dataset provides methane flux estimates derived from airborne measurements collected over Alaska and the western Yukon Territory during the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) between 2012 and 2014
  • Biodiversity Functions | NASA Earthdata
    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
  • AirMOSS: L4 Daily Modeled Net Ecosystem Exchange (NEE . . . - Earthdata
    This data set provides Level 4 daily estimates of Net Ecosystem Exchange (NEE) of CO2 at a spatial resolution of 30 arc-seconds (~1 km) for seven of the sites covered by the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) flights, each site spanning ~2500 km2
  • ISLSCP II Ecosystem Rooting Depths | NASA Earthdata
    In response to this challenge, a data set of vertical rooting depths was collected from the literature in order to construct maps of global ecosystem rooting depths The parameters included in these data sets are estimates for the soil depths containing 50% and 95% of all roots, termed 50% and 95% rooting depths (D50 and D95, respectively)
  • PalEON: Terrestrial Ecosystem Model Drivers for the . . . - Earthdata
    This dataset from the PalEON Ecosystem Model Intercomparison Project (PEMIP) provides harmonized regional environmental and meteorological drivers at a resolution of 0 5 degrees for the North-central and Northeastern U S over the time period 0850-01-01 to 2010-12-31
