   The eddy covariance technique has become the most useful method to quantify ecosystem carbon sequestration. Complex terrain and complicated canopy structure create difficult conditions that can induce non-ignorable advection errors during calm nights. Both advection experiments and model simulations have demonstrated that the signs/magnitudes of advection flux components are related to the tower-location over complex terrain. We intend to use a seven tower setup to examine simultaneously several typical advection problems on a single forested hill in the Black Rock Forest (BRF). 
We will use the existing BRF tower on the hill top
