Abstract In Southern Brazil, rice paddies are an important agribusiness occurring in lowlands, where the growing season occurs in the summer and the area remains without use in the rest of the year. We estimated the surface fluxes (carbon dioxide (CO 2 ), Latent (LE) and Sensible (H) heat fluxes) over a flooded rice paddy in Southern Brazil for a five-year period using the eddy covariance methodology. LE was higher than H, with mean values of the Bowen ratio (H LE −1 ) of 0.14 during the growing...

This study investigated the potential of assessing the water balance in South America, at multiple scales in South America, using satellite remote sensing precipitation and evapotranspiration datasets, terrestrial water storage changes from Gravity Recovery and Climate Experiment (GRACE) and discharge measurements. The remote sensing precipitation datasets included those of the Tropical Rainfall Measuring Mission (TRMM) and the Multi-Source Weighted-Ensemble Precipitation (MSWEP), whilst the ET ...

Abstract. In this study, Taylor statistical diffusion theory and sonic anemometer measurements collected at 11 levels on a 140-m high tower located at a coastal region in southeastern Brazil have been employed to obtain quasi-empirical convective eddy diffusivity parameterizations in a planetary boundary layer (PBL). The derived algebraic formulations expressing the eddy diffusivities were introduced into an Eulerian dispersion model and validated with Copenhagen tracer experiments. The employed...

Evapotranspiration is an important phenomenon to agriculture; therefore, this work aims at verifying the suitability of the SEBAL and METRIC models to estimate latent heat flux using remote sensing data from grain cultivation areas in the northwestern subtropical region of Rio Grande do Sul. This region stands out for grain production. The analyzed data set consisted of 84 dates distributed over a 3-year period of areas planted with soy, corn, oats, wheat, and vetch crops. The data estimated fro...

The aim of this work is to perform an analysis of the CO2 relationship between nocturnal fluxes of soil and ecosystem, in na agroecossystem as atmospheric variables (soil temperature, solidity, and singleness), under the soya tillage system in southern Brazil. To calculate the fluxes, automatic soil chamber system and the EddyCovariance system were used. The preliminary analysis showed that soil moisture controls the emission of CO2 and the CO2 cumulative flux of the soil is greater than the atm...
