Relação entre transparência da água obtida in situ e a reflectância da imagem landsat 5 tm do reservatório Passo Real
(Universidade Federal de Santa Maria, 2014-01-21)
The water quality monitoring is generally done from in situ sampling. However, the financial operational cost is high, beyond the difficult sampling in different sectors of the hydric body. As a possible solution for this ...
Fluxos de calor e dióxido de carbono entre o oceano e a atmosfera na região costeira e oceânica ao Sul do Brasil
(Universidade Federal de Santa Maria, 2014-07-11)
The Southwest Atlantic Ocean is characterized, in winter, by the presence of an
oceanographic front between the Brazil Current (BC) and the Brazilian Coastal Current
(BCC). The BC/BCC oceanographic front generates intense ...
Desenvolvimento de um piranômetro baseado em componentes semicondutores
(Universidade Federal de Santa Maria, 2014-02-27)
This master of science thesis was developed from the idea of research
and the production of a pyranometer of easy construction and low cost. This work
presents research to develop a sensor in order to quantify the intensity ...
Parametrização de turbulência na previsibilidade de temperaturas mínimas em um modelo de mesoescala
(Universidade Federal de Santa Maria, 2014-06-02)
The present study aims to evaluate the quality of nocturnal temperature forecast
made by a mesoscale numerical model and to understand the reasons behind the difficulties
found. To do that, the Weather Research and ...
Parametrizações convectivas no modelo WRF e sua relação com a precipitação durante ciclogêneses no sudeste da América do Sul
(Universidade Federal de Santa Maria, 2014-02-25)
The Weather Research and Forecasting (WRF) model is used in the simulation of
26 cases of cyclogenesis in southeastern South America, on the cyclogenetic region near
the La Plata River mouth. The simulations comprised ...
Identificação e quantificação de áreas de conflito de uso da terra em APP no rio Ibicuí-Mirim
(Universidade Federal de Santa Maria, 2014-07-09)
This study sought to expose the reality of permanent preservation areas along part of the River drainage Ibicuí-Mirim, identifying and quantifying land use conflicts. Through GIS techniques, areas around (buffers) were ...
Análise de diferentes métodos de preenchimento de falhas nos fluxos de CO2: estimativas sobre o arroz irrigado
(Universidade Federal de Santa Maria, 2014-02-13)
The net exchange of CO2 between the atmosphere and the ecosystem (NEE), represent the balance of the ecosystem respiration (Reco) and gross primary production (GPP), which are directly related to temperature and photosynthetic ...
Bloqueios atmosféricos e sistemas frontais sobre a América do Sul em cenários de clima futuro
(Universidade Federal de Santa Maria, 2014-02-20)
The meteorological systems modulate the behavior of rainfall and temperature on
large regions and must be correctly simulated by the climate models. The representation of
these events should be good for the reliability ...
