Spectral Reflectance of Tundra Plants

Common Garden Ecotype site.

A plot at a common garden ecotype site near Eagle Creek, Alaska. Common garden sites were established with different populations of the tussock-forming sedge taken from different latitudes in Alaska.

ABoVE: Reflectance Spectra of Tundra Plant Communities across Northern Alaska

This new dataset provides full-spectrum (350-2500 nm) reflectance measurements of plants from across northern Alaska during the summer 2017 and 2018 Arctic-Boreal Vulnerability Experiment (ABoVE) field seasons. Plot-level reflectance data include an assemblage of vascular and non-vascular species comprising tundra plant communities, while leaf-level scans are included for particular tundra species. Sampling methods and data and metadata structure follow that of the Ecological Spectral Information System (EcoSIS) Spectral Library. Full-spectrum reflectance measurements of plant communities at the leaf and plot scales enables integration with other remotely sensed spectral data for scaling up to watershed, regional, and global scale earth system models.

ABoVE is a NASA Terrestrial Ecology Program field campaign conducted in Alaska and western Canada between 2016 and 2021. See all ORNL DAAC data from ABoVE.
