Increasing atmospheric CO 2 concentration decreases stomatal conductance in many species, but the savings of water from reduced transpiration may permit the forest to retain greater leaf area index ( L ). Therefore, the net effect on water use in forest ecosystems under a higher CO 2 atmosphere is difficult to predict. The free air CO 2 enrichment (FACE) facility ( n = 3) in a 14‐m tall (in 1996) Pinus taeda L. stand was desig...

One of the main challenges to quantifying ecosystem carbon budgets is properly quantifying the magnitude of night‐time ecosystem respiration. Inverse Lagrangian dispersion analysis provides a promising approach to addressing such a problem when measured mean CO 2 concentration profiles and nocturnal velocity statistics are available. An inverse method, termed ‘Constrained Source Optimization’ or CSO, which couples a localized...
