As part of the Global Tropospheric Experiment/Amazon Boundary Layer Experiment 2A, micrometeorological measurements were made using a 45 m scaffolding tower located in the Ducke Reserve Forest site (2{degree}57{prime}S, 59{degree}57{prime}W) 26 km northeaster of Manaus, Amazonas, Brazil. The authors report the daily variation within and above the forest of several meteorological parameters such as temperature, humidity, winds, radiation exchange, and energy partition into latent and sensible heat fluxes. Estimates of eddy diffusivity coefficients for momentum, heat, and water vapor were made using the observed profiles. These results provide information on the physical processes involved in the exchange of momentum, heat, and water vapor between the forest and the air layer above. To account for the anomalies in eddy diffusivities, a brief discussion is presented based on turbulent transport processes.
