Short summary
Bias and uncertainty in Hg flux measured by micrometeorological methods (MM) and dynamic flux chambers (DFCs) are assessed from two field inter-comparison campaigns. DFC flux bias follows a diurnal cycle due to modified temperature and radiation balance inside the chamber. The precision in concentration difference measurements poses critical constraint on obtaining a larger fraction of significant MM flux. Asynchronous sampling impairs flux accuracy under varying atmospheric Hg concentration.
