You are cordially invited to the seminar of Dr. Laura Duncanson (Biospheric Sciences Lab, NASA Goddard Space Flight Center), organized by CAVElab in the framework of the belspo project 3D-FOREST.

This is the second out of two seminars about the upcoming NASA GEDI mission.


Despite the recognized importance of forests in the global carbon cycle and climate system, the magnitude and distribution of forest carbon content remains unknown. This is largely due to a dearth of remote sensing data specifically designed to capture forest above ground structure, and several upcoming spaceborne missions have been designed specifically to address this problem.

NASA’s GEDI and ICESAT-2, NASA/ISRO’s NISAR mission, JAXA’s MOLI and ALOS-4, and ESA’s BIOMASS missions will all capture different information about forest structure that will be used to independently or synergistically map above ground biomass.

This exciting suite of upcoming missions also presents a unique set of challenges – how can these missions work together to develop biomass models, validate biomass products, and capitalize on the information content from other missions?

This presentation will give the example of biomass modeling and mapping from NASA’s GEDI mission, including exploring how many equations/strata are required to describe Earth’s forests, which empirical modeling approaches are most successful, and how GEDI’s calibration and validation system can be used for other upcoming missions.

Finally, an overview of the Committee on Earth Observing Satellites (CEOS)’s new focus area on calibration and validation of above ground biomass will be provided.
