    "abstract": "In this paper, we discuss the impact of a rain forest canopy on the\nstatistical characteristics of atmospheric turbulence. This issue is of\nparticular interest for understanding on how the Amazon terrestrial biosphere\ninteract with the atmosphere. For this, we used a probability density function\nmodel of velocity and temperature differences based on Tsallis\u0027 non-extensive\nthermostatistics. We compared theoretical results with experimental data\nmeasured in a 66 m micrometeorological tower, during the wet-season campaign of\nthe Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).\nParticularly, we investigated how the value of the entropic parameter is\naffected when one moves into the canopy, or when one passes from day/unstable\nto night/stable conditions. We show that this new approach provides interesting\ninsights on turbulence in a complex environment such as the Amazon forest.",
