O papel da generalização digital na segmentação de imagens.
Algoritmos de segmentação e classificação detectam feições presentes em imagens, produzindo conjuntos de dados vetoriais compostos por polígonos. Um processo de generalização é necessário para gerar mapas com diferentes graus de detalhe em diferentes escalas e reduzir o armazenamento de d...

Uncoupled variations of the tropical equatorial climate in a coupled ocean-atmosphere model.
This communication evaluates the mechanisms associated with the inherent difficulty of global coupled ocean-atmosphere models to simulate the thermal vertical structure of the equatorial Atlantic. The study is done with use of the coupled GCM developed at CPTEC, which consists of CPTECs global atmos...

CO and CO2 gradients across the Amazon during the BARCA campaign.
Carbon Monoxide (CO) is emitted to the atmosphere over the Amazon by biomass combustion as well as being formed by oxidation of hydrocarbons. Carbon dioxide (CO2) is emitted by combustion and respiration and absorbed by photosynthesis. CO and CO2 mixing ratios were measured continuously at Maxarangu...

Assimilation of air-borne aerosol measurements in Central Brazil during the 2007 burning season using the regional CCATT-BRAMS model.
In Central Brazil every year large areas of forest, cerrado and pasture land are burned emitting primary carbonaceous aerosols into the atmosphere. These interfere with the radiative budget, affecting directly the amount of solar radiation that is reflected and scattered back to space, and partly ab...

River corridors of the Amazon Basin and their response to anthropogenic change: a look back and a glimpse forward.
In 1997 scientists proposed an agenda for biogeochemical research in river corridors of the Amazon basin to both identify gaps in knowledge and to outline a possible approach to filling those gaps. Most previous research in the Amazon had focused on natural processes with a majority of effort on the...

Medidas de dióxido de enxofre utilizando um espectrofotômetro Brewer em Cubatão – SP, Brasil.
The study of atmospheric trace gases is increasing over the years. One of these gases is sulfur dioxide (SO2), which is found in the troposphere and stratosphere, as a result of both natural and anthropogenic emissions. A campaign was made in Cubatao-SP, from 04/12/2007 to 08/07/2007, to measure the...
