Towards a dynamic geospatial database model.
This document aims to present: (1) an analysis of distinct geospatial data dynamics and real application demands on representing and querying spatio-temporal data; and (2) a critical review of ten spatio-temporal database models proposed in the literature during the past two decades. This is an init...- por Portal Padrão

Experiments using new initial soil moisture conditions and soil map in the Eta model over La Plata Basin.
Strong interactions between soil moisture and the atmospheric processes take place in all spatial and temporal scales. The effects of soil moisture on rainfall can be associated with dynamical modifications of atmospheric systems as well as the generation of mesoscale circulations through the format...- por Portal Padrão

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
