The effects of the spatial resolution of airborne lidar data on aboveground biomass estimation.
The amount of aboveground biomass (AGB) held in vital components of vegetation play a significant role in the carbon cycle of tropical forests. Reducing uncertainty of terrestrial carbon cycle depend strongly on the accurate estimate of AGB. Lidar remote sensing provides the most precise methodology...- por Portal Padrão

Testes de sensibilidade para diferentes parametrizações cumulus do modelo wrf para melhorar as estimativas de vento.
A avaliação do regime de vento de forma confiável para uma determinada região por meio de coleta de dados com precisão adequada apresenta um alto custo financeiro. Os modelos meteorológicos de mesoescala são ferramentas que demandam investimentos relativamente baixos e vem apresentando result...- por Portal Padrão

Estimating the likelihood of an Amazon forest dieback and potential socio-economic impacts.
Almost 20 years ago, the Amazon forest-dieback hypothesis has been proposed indicating that a large-scale loss of Amazon rainforest may be caused by climate change which may lead to substantial changes in ecosystem functioning and structure. Here, we revise the likelihood of a potential Amazon fores...- por Portal Padrão

Synthesis of nitrogen fixation rates across major biomes in Latin America.
Biological nitrogen fixation (BNF) is the main pathway by which nitrogen (N) is delivered to unmanaged ecosystems. Despite the importance of BNF on understanding and modeling key ecosystem functions such as carbon storage and climate feedbacks, information on BNF rates for natural ecosystems in Lati...- por Portal Padrão

Effect of land use and land cover on greenhouse gas emissions from peatlands in the Paraíba Valley, Brazil.
Peatlands cover around 570 million hectares worldwide and although most are located in boreal environments, tropical peatlands cover 170 million hectares and store about 860 Gt of carbon. Peat soils store a large amount of carbon and have acted as sinks of atmospheric CO2 for thousands of years but ...- por Portal Padrão

Observation of a lightning flashover with a high-speed video camera.
In this paper we analyze images of a lightning flashover induced by a downward negative lightning flash that struck a transmission line located in São Paulo, Brazil. The lightning flash and the flashover were recorded by a high-speed camera running at 10,000 images per second. The approach of the n...- por Portal Padrão
