High Levels of CO2 Exchange During Synoptic-Scale Events Introduce Large Uncertainty Into the Arctic Carbon Budget
CO2 release from thawing permafrost is both a consequence of, and a driver for, global warming, making accurate information on the Arctic carbon cycle essential for climate predictions. Eddy covariance data obtained from Bayelva (Svalbard) in 2015, using well-established processing and quality contr...
