As medias diarias de carbono (C-CO) foram investigadas em um sitio de cultura de arroz irrigado no Sul do Brasil: Cachoeira do Sul (2010-2012). Os dados experimentais foram obtidos atraves da tecnica de covariância de vortices. A assimilacao de CO variou com o desenvolvimento da cultura, exibindo uma tendencia similar entre os anos de cultivo. Durante a fase VJ, o NEE manteve-se positivo. Para as seguintes fases (VA e R), foi observado um aumento no NEE durante o dia. Na fase final do cultivo do...

In the stable stratified atmospheric boundary layer, spectra might be affected by several kinds of waves. Since the problem of turbulent diffusion is closely related to the spectra of wind velocity fluctuations, it is necessary to separate the contributions of those waves from that of turbulence. Discrete wavelet packets transform was applied to temperature and vertical velocity fluctuations measured in Candiota, RS (31 ° 28´ S, 53 ° 40´ W), sampled with a frequency of 10 Hz and 1 Hz. In these d...
