The role of natural fires in tropical South American biomes.

In the past few decades, the role of natural and human-induced fire regimes and disturbances have received considerable attention in ecosystem studies. Most investigations focus on anthropogenic fire disturbances particularly associated to tropical degradation in South America, mostly due to croplan...

Ozone budget in the lower troposphere over Amazonia.

During LBA/BARCA (Balanço Atmosférico Regional de Carbono na Amazônia) field experiment, measurements of several trace gases and aerosols were made onboard INPE's "Bandeirante aircraft". Flights transected the Amazon basin from the Tropical Atlantic Ocean shore to the northwestern part of the Ama...

Aspects of the resilience of Amazon ‘biome services’ to climate change and deforestation.

The Amazon biome provides multiple environmental services, of which maintaining water cycles, conserving carbon stocks and biodiversity are among the most important. This biome system is under threat and often seen as extremely vulnerable. Several lines of evidence, however, suggest that the system ...

Melhoria do inventário de emissões para a modelagem da qualidade do ar em Cuba.

Emission data is an important source of uncertainties in chemical weather forecast. In particular, when only global inventories, or any inventory that doesnt consider the specifics of local data, is used. An improved emission inventory was included into the CCATT-BRAMS emission preprocessor, includi...
