Advancing the predictive power of Earth system models through understanding
of the structure and function of Arctic terrestrial ecosystems
Progress & Accomplishments
Mapping Arctic Plant Functional Type Distributions in the Barrow Environmental Observatory Using WorldView-2 and LiDAR Datasets
NGEE Arctic researchers combined high-resolution multi-spectral remote sensing imagery from the WorldView-2 satellite with light detecting and ranging (LiDAR)-derived digital elevation models (DEMs) to characterize the tundra vegetation around the BEO.
Significant methane oxidation activity was observed in incubations of flat-centered polygon transitional soil and permafrost layers, which also exhibited high levels of methane production activity under anoxic conditions.
Demonstration of CLM-PFLOTRAN Coupling Lays a Foundation for Biogeochemistry Simulation Across Scales
An implicit time-stepping model for decomposition, nitrification, denitrification, and plant nutrient uptake was implemented in the Community Land Model (CLM), the land ecosystem component of a coupled Earth System Model.
