Estudo das emissões de óxido nitroso no cultivo de soja.
Este trabalho teve como objetivo apresentar medidas de óxido nitroso (N2O) emitido em cultura de soja (Glycine max) com a utilização da bactéria Rizobium, a qual que tem o objetivo de fixar o nitrogênio da atmosfera para a planta, evitando que seja necessária a adubação nitrogenada. A técni...- por Portal Padrão

Network of environmental sensors in tropical rain forests.
The interaction between the Earths atmosphere and the terrestrial biosphere plays a fundamental role in the climate system and in biogeochemical and hydrological cycles, through the exchange of energy and mass (for example, water and carbon), between the vegetation and the atmospheric boundary layer...- por Portal Padrão

TerraLib 5.0: supporting data-intensive GIScience.
An increase of geo-spatial data availability due to recent technological advances in data acquisition instruments (GPS, Sensor Networks, Remote Sensing Satellites), has brought Geo-Information Science researchers to the following scenario: a huge amount of data to carry out their research as opposed...- por Portal Padrão

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...- por Portal Padrão

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...- por Portal Padrão

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...- por Portal Padrão

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...- por Portal Padrão
