Arctic-Boreal Vulnerability above.nasa.gov ABoVE is a large-scale NASA-led study of environmental change in arctic & boreal regions and the implications for ecological systems and society Our overarching Science Question is How vulnerable or resilient are ecosystems and society to environmental change in the arctic and boreal region of western North America? above.nasa.gov 3 The Carbon Cycle & Ecosystems Office is responsible for implementation and management of ABoVE Science team members work closely with the CCEO and rely upon our guidance for field operations and safety, communications with local and regional stakeholders and authorities, and utilization of ABoVE cyberinfrastructure. The ABoVE Science Cloud combines high performance computing with emerging technologies, such as analytics, and data management tools for analyzing and processing geographic information to create an environment specifically designed for large-scale modeling, analysis of remote sensing data, copious disk storage for big data with integrated data management, and integration of core variables from in-situ networks. 44

19 Projects: Estimated Biomass in South Sahara Using NGA data to estimate tree and bush biomass over the entire arid and semi-arid zone on the south side of the Sahara Project Summary: Estimate carbon stored in trees and bushes in arid and semi-arid south Sahara Establish carbon baseline for later research on expected CO2 fertilization of photosynthesis will first be manifested in the arid and semi-arid zones, because bushes and trees will use less water to grow, thus growing more Replicate technique globally (i.e., Arctic where bushes and shrubs are moving into the tundra because of warmer conditions) Proven successful method can be expanded for all
arid and semi-arid areas of the planet if successful Principal Investigator: Compton J. Tucker, NASA Goddard Space Flight Center Shadow Tree Crown NGA Imagery representing tree & shrub automated recognition 20 ABoVE Data Management at CISTO ArcGIS Desktop and Portal ABoVE Users Account Setup User
