Abstract

Using vertical profiles of atmospheric components, collected in the Amazon Basin region, we will try to broaden our understanding of key elements regarding carbon balance in the atmosphere-biosphere through spatio-temporal patterns of tropospheric greenhouse gas concentration, and considering carbon transport in the atmosphere and on the surface of the Amazon basin. Then, we will seek to scale the contributors of various systems that compose this balance, identifying and ranking, in a regional scale, the key factors that define carbon fluxes. The carbon balance of any given region is calculated based on the surface variations, land use and the ecophysiological vegetation dynamics. Investigative tools applied to distribution of water bodies and flood areas, fire occurrence, deforestation, physiological functioning of vegetation, etc., are critical to mapping the different contributors to carbon balance. This regional dimensioning contributes substantially, to the analysis of the resulting CO2 concentration variation in atmospheric profile. 8.6.2 Objectives: Based on a high precision 5-year database (expandable for an additional 5 years) of vertical profiles of greenhouse gases from various sites of the Amazon Basin region (Gatti et al., 2014), and with calculations results of carbon balance on the surface (Ometto et al., 2014), we will find differences and similarities in the assessment of atmospheric CO2 concentrations variation in the Amazon Basin, thus expanding our scientific understanding of the processes that control carbon exchange and climate response over time scales, in this strategic ecological region
