Aerosol optical thickness influence over the Photosynthetically Active Radiation (PAR) in earth surface – I.
The atmosphere is made up of several components, among them are present solid and liquid particles in suspension called aerosols. Aerosols make an important role by absorbing and reflecting radiation from space. The work aims to evaluate the relationship between aerosols and Photosynthetically Activ...- por Portal Padrão

Assessment of the energy balance of forest and “caatinga” sites in Brazil from SSiB and IBIS models.
Changes in land surface properties, often associated with changing vegetation and soil characteristics, have dramatic effects on the climate simulated by general circulation models (GCMs). Thus, during the last several years efforts are aimed to evaluating land surface parameterizations. Currently, ...- por Portal Padrão

Modelos dinâmicos espaciais em programação funcional.
Modelos espacialmente explícitos são simulações computacionais que descrevem algum fenômeno que tem uma ocorrência bem definida no espaço e no tempo. Desse modo, o desflorestamento é um fenômeno espaço temporal. Ele ocorre em uma determinada localização no espaço e no tempo. Então, é ...- por Portal Padrão

A basin-wide intercomparison of ecosystem land surface models and carbon and water flux observations in Amazonia.
The Amazon forest plays an important and complex role in the global water and carbon cycle, and important advances have been made in understanding the underlying processes in recent years. However, reconciling modeled mechanisms with observations across scales remains a challenge. To better address ...- por Portal Padrão

Variação decadal do ciclo anual de precipitação em áreas urbanas no leste de São Paulo.
Based on studies of the United Nations Population Fund (UNPA), 82% of South America populations live in urban areas as of 2007, with a rate of growth about 1,7% a year. In Brazil, 70% of the population lives in the area originally covered by the Atlantic Forest (Mata Atlântica). The urban sprawl ha...- por Portal Padrão
