Fluxo de metano na atmosfera sobre uma cultura de arroz irrigado por inundação no sul do Brasil
(Universidade Federal de Santa Maria, 2016-08-10)
The rice paddy is responsible for 12-16% of the anthropogenic emission of CH4 in the
world. Brazil is one of most important rice paddy producer. The goal of this study is to
understand the dynamics of methane exchange ...
Não-estacionariedade de séries temporais turbulentas e a grande variabilidade dos fluxos nas baixas freqüências
(Universidade Federal de Santa Maria, 2011-08-11)
Turbulent flow high complexity makes it difficult to describe complex phenomena,
such as the transport of vector and scalar quantities at the lower atmosphere,
making the analysis of experimental data, such as time series, ...
Modelo simplificado para turbulência na camada limite noturna
(Universidade Federal de Santa Maria, 2016-03-08)
The appropriate estimation of turbulent fluxes in very stable conditions is a great challenge
for numerical models that simulate the average behavior of the stable boundary layer.
Although many features of the flow are ...
Avaliação do método do balanço da camada limite para a estimativa de fluxos turbulentos noturnos
(Universidade Federal de Santa Maria, 2006-10-27)
This work is about to verify the performance of the boundary layer budgeting method as alternative for measuring the surface turbulent fluxes in conditions that allow the
validation of the measurements with data taken ...
Fluxos turbulentos de CO2 em uma área de arroz irrigado no RS
(Universidade Federal de Santa Maria, 2007-11-28)
This thesis quantifies the net change of CO2 (NEE) in an irrigated rice crop cultivation in
RS (Brazil). The research is part of the project CT-HIDRO, which presents as main purpose the
description of surface conditions ...
