文摘

EC measurements above and below an open forest canopy reveal frequent decoupling. Above-canopy filtering approaches identify decoupled periods insufficiently. Local topography may have a profound influence on above-canopy EC measurements. Decoupling and sub-canopy horizontal flow may bias forest EC measurements globally.
