Description:
During summer 2006 eddy correlation CO2 fluxes were measured in the Greenland Sea using a novel system set-up with two shrouded LICOR-7500 detectors. One detector was used exclusively to determine, and allow the removal of, the bias on CO2 fluxes due to sensor motion. A recently published correction method for the CO2-H2O cross-correlation was applied to the data set. We show that even with shrouded sensors the data require significant correction due to this cross-correlation. This correction adjusts the average CO2 flux by an order of magnitude from −6.7 × 10−2 mol m−2 day−1 to −0.61 × 10−2 mol m−2 day−1, making the corrected fluxes comparable to those calculated using established parameterizations for transfer velocity.
