Long-Term Release Of Carbon Dioxide From Arctic Tundra Ecosystems In Alaska

by -

Releases of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from thawing permafrost are expected to be among the largest feedbacks to climate from arctic ecosystems. However, the current net carbon (C) balance of terrestrial arctic ecosystems is unknown. Recent studies suggest that these ecosystems are sources, sinks, or approximately in balance at present….

Bayesian Optimization Of The Community Land Model Simulated Biosphere–Atmosphere Exchange Using Co2observations From A Dense Tower Network And Aircraft Campaigns Over Oregon

by -

The vast forests and natural areas of the Pacific Northwest compose one of the most productive ecosystems in the Northern Hemisphere. The heterogeneous landscape of Oregon poses a particular challenge to ecosystem models. This study presents a framework using a scaling factor Bayesian inversion to improve the modeled atmosphere–biosphere exchange of CO2. Observations from five… More
