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 ...

Improving the representation of tropospheric aerosols over South America in an Atmospheric chemistry model by three dimensional variational data assimilation.
The aerosol and trace gas three dimensional variational data assimilation system (3D-VAR) of CCATT-BRAMS, the Coupled Chemistry-Aerosol-Tracer Transport model coupled to the Brazilian developments on the Regional Atmospheric Modeling System (BRAMS) will be presented. In the framework of a case study...

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...

Although sugarcane crop is admittedly relevant to Brazilian economy, the increase of ethanol demand may produce significant environmental impacts. The common practice of pre-harvest burning of sugarcane straw emits particulate material, greenhouse gases, and tropospheric ozone precursors to the atmo...
