Projekt badawczy

The Amazon Basin plays a key role in carbon and water cycles, climate change, atmospheric chemistry and biodiversity. As a result, studies on the dynamics of the coupling mechanisms of turbulent flows between the biosphere and atmosphere are important. They aim to better understand the functioning of vegetation during different times of the year and thermal stratification, in order to provide subsidies that will contribute to improving the management, sustainability, mitigation and adaptation of these ecosystems in the face of climate change. Therefore, this project aims to determine and characterize the structure, variability and dynamics of the planetary boundary layer (CLP); its variability in turbulent flows of energy, momentum and chemical species for a preserved forest area in central Amazonia. It is known that the height of the PLC also controls the ?box volume? within which the mixing and dispersion of Greenhouse Gases (e.g. CO2, CH4, N2O, etc.), aerosol particles, ozone, etc. occur. Therefore, characterizing the characteristics of the CLP, especially its height, is crucial in the pollutant dispersion process, where studies suggest that concentrations of NO, NO2, NOx and PM2.5 are correlated with the heights of the CLP. To carry out this study, experimental data obtained through in situ and remote sensors installed at the ATTO site will be used. High-resolution numerical simulations will also be carried out using the LES-PALM model. The simulations aim to obtain a better understanding of the dynamics of turbulent exchange processes of energy and matter both within and above the forest canopy for different CLP structures, associating them with the chemical part of the atmosphere.
