and temperature variance. These have ...
Utilização do índice de área foliar obtido por sensoriamento remoto para a estimativa da evapotranspiração de referência na bacia do Prata
(Universidade Federal de Santa Maria, 2010-03-15)
In this work the estimate of evapotranspiration over the region of the Plata Basin, using data of leaf area index obtained from remote sensing, through the MODIS. The method used to obtain the estimated evapotranspiration ...
Derivação de um skewness da velocidade vertical turbulenta a partir de um modelo LES
(Universidade Federal de Santa Maria, 2010-08-13)
The planetary boundary layer (PBL) is a physical system presenting a variety of complex states characterized by the turbulence phenomenon. An understanding of the
turbulence patterns and its structural details is of ...
