This is a large project funded by NASA as a component of the Large Scale Atmosphere-Biosphere Experiment in Amazonia (LBA). Our study is using eddy covariance to directly measure the effects of selective logging on the CO2 and energy exchange of an evergreen tropical forest in Brazil.

We started flux measurements in June 2000 at the top of a 65-m tower, which extends 10 to 20 m above the surrounding forest.  The forest near the tower was relatively undisturbed, and remained so until the 2001 dry season (July to November), when a 1000 ha patch upwind of the tower was selectively logged.  The observations prior to the cut provide a baseline characterization of the CO2 and energy exchange by undisturbed forest.
