             abstract = "We analyzed the probability density function (PDF)of velocity and 
                         temperature differences in the canopy sublayer of Amazonia based 
                         on Tsallis' generalized thermostatistics theory. We show that such 
                         a theory provides an accurate framework for modeling the 
                         statistical behavior of the inertial subrange above and below the 
                         canopy. For this, we compared the experimental PDFs with the 
                         theoretically predicted ones. The data were measured during the 
                         wet season of the Large-Scale Biosphere-Atmosphere Experiment in 
                         Amazonia (LBA), which was carried out during the months of 
                         January-March 1999 in the southwestern part of Amazonia region. 
                         Measurements were made simultaneously at different heights in a 60 
                         m micrometeorological tower located in the Biological Reserve of 
                         Jaru (10degrees04'S, 61degrees56'W), Brazil. The fast response 
                         wind speed measurements, sampled at 60 Hz rate, were made using 
                         three-dimensional sonic anemometers at the heights of 66 m (above 
                         the canopy)and 21 m (below the canopy). The results showed good 
                         agreement between experimental data measured above the canopy 
                         forest and Tsallis' generalized thermostatistics theory. For below 
                         canopy data, the agreement between experimental and theoretical 
                         PDFs was fairly good, but some distortion was observed. This is 
                         probably due to some peculiar characteristics of turbulent 
                         momentum transfer process inside the forest crown. Discussion is 
                         presented to explain these results. Conclusions regarding the 
                         absence of {"}universal scaling{"} in the inertial subrange are 
                         also presented in the context of the entropic parameter of 
                         Tsallis' theory.",
