                         measured from a 60m high tower in the Rebio-Jaru forest (10 
                         degrees 04.7S, 61 degrees 52.0W), located in the Brazilian 
                         northwestern state of Rondonia. The data were collected during the 
                         wet season as part of an intensive campaign of the large scale 
                         biosphere-atmosphere experiment in Amazonia. Nine cup anemometers 
                         were vertically placed to provide a good estimate of the 
                         inflection point height of the mean wind velocity profile. The 
                         resulting data were used to formulate a mean vertical wind speed 
                         profile, (u) over bar (z), based on key parameters such as the 
                         inflection point height and the leaf area index. The modified 
                         hyperbolic tangent function was used to provide a more flexible 
                         fit to the experimental data. An exponential term was also added 
                         to the (u) over bar (z) function, so that it can assume the 
                         appropriate s' shape near the ground. Thus, some parameters were 
                         incorporated into the analytical profile function to enable more 
                         flexibility. The presented results demonstrate that the profile is 
                         a good fit to the experimental data measured above and within the 
                         Amazon forest canopy.",
