Long term measurements of the elemental composition and optical properties of a...
Arana, Andréa A.; Artaxo, Paulo; Rizzo, L. V.; Bastos, WanderleiAerosols are being collected and analyzed for trace elements in two sites in Amazonia since January 2008. On eof the site, Manaus is located in a very pristine area in Central Amazonia. The site is nt affected directly by any urban plume for thousands of kilometers. A second site is located in Porto Velho, in a region with heavy land use change and deforestation. Optical properties (light scattering ad absorpti...
Atmospheric aerosols in Amazonia and land use change: From natural biogenic to ...
Artaxo, Paulo; Rizzo, Luciana Varanda; Brito, Joel F.; Barbosa, H. M. J.; Arana, Andréa A.; Sena, E. T.; Cirino, Glauber G.; Bastos, WanderleiIn the wet season, a large portion of the Amazon region constitutes one of the most pristine continental areas, with very low concentrations of atmospheric trace gases and aerosol particles. However, land use change modifies the biosphere-atmosphere interactions in such a way that key processes that maintain the functioning of Amazonia are substantially altered. This study presents a comparison between aerosol ...
