The Joint Global Carbon Cycle Center is active in large-scale, long-term field campaigns. As an example Joint Global Carbon Cycle Center researchers have prominent roles in the NASA-sponsored Arctic-Boreal Vulnerability Experiment (ABoVE). Arctic and boreal ecosystems present some of the major uncertainties in the carbon cycle. ABoVE aims to improve our understanding about the carbon cycle in higher latitudes, focusing on the impacts of climate change on high northern latitude ecosystems, including tundra, boreal forests, and peatlands
