The peak at Dahra was xA g xA C

Goulden et al., 1996). We assessed the errors associated with the filtering (Efilt) by calculating annul balances by using different threshold criterias for the overall quality flags (threshold values: 1–6).A commonly acknowledged systematic source of error is the insufficient coverage of high frequencies (Efreq) contributing to the fluxes. An uncertainty of 30% for the correction procedure of the loss of high frequencies were assumed following Aurela et al.
