TY - T1 - High-quality eddy-covariance CO2 budgets under cold climate conditions SN - / UR - http://hdl.handle.net/10138/307196 T3 - A1 - Kittler, Fanny; Eugster, Werner; Foken, Thomas; Heimann, Martin; Kolle, Olaf; Göckede, Mathias A2 - PB - Y1 - 2017 LA - eng AB - This study aimed at quantifying potential negative effects of instrument heating to improve eddy-covariance flux data quality in cold environments. Our overarching objective was to minimize heating-related bias in annual CO2 budgets from an Arctic permafrost system. We used continuous eddy-covariance measurements covering three full years within an Arctic permafrost ecosystem with parallel sonic anemometers operation with activated heating and without heating as well as parallel operation of ope...
