The balance of radiation represents the energy gains and losses on the surface, and can be estimated by summing the four components of surface radiation (incident and reflected solar radiation, radiation emitted by the surface and emitted by the atmosphere). The SiB2 model represents ecosystems and provides estimates of surface energy changes. In this work, five different incident long wave estimation equations were tested to verify the influence of this component on the closure of the radiation...

In this study, the eddy-covariance technique was used to estimate the surface fluxes of carbon (CO2) and energy, in the latent (LE) and sensible (H) forms, over a native field ecosystem (pasture). The results show that the ecosystem in question presents a predominant seasonality in its ecological functioning, especially regarding the observations of the LE and CO2 fluxes, with carbon assimilation and evapotranspiration with maximum values during the summer. During the winter season observations ...

One of the main components of water and energy balance in terrestrial ecosystems, the evapotranspiration (ET), was estimated using the eddy covariance technique. To better understand these energy transfer processes it is necessary to know how the ET responds to different meteorological variables. The main objective of this work is to investigate the hysteresis response of ET to environmental variables including air temperature (Temp), vapor pressure deficit (DPV) and net radiation (R n ) at a di...

The atmospheric longwave radiation is a fundamental quantity in calculating the radiation balance at the surface. Measures of this magnitude in the gaucho Pampas region are scarce. An alternative estimate for this variable is the use of classical equations that use air temperatures and steam pressure. The objective of this study was to evaluate the performance of five equations in the estimation of the long atmospheric wave radiation for a clear day on a Pampa biome located in Santa Maria-RS. At...

The eddy covariance technique was used to estimate the sensible and latent heat flux between the atmosphere and the Pampa Biome in the period from 20 November 2013 to 20 November 2014. Annual Evapotranspiration (ET) was 1021 mm, corresponding to 55% of the annual precipitation. The ET is highly correlated with the net radiation (97%). The Bowen ratio was indicated that most of the available energy was used for the evaporation. The evaporative fraction remained about average, with greater variabi...

In this work, an analysis of the uncertainty of energy flux resulting from post-closure methods of the energy balance: H Method, LE method and Bowen method for the data observed in native grass area of the Pampa biome, located in Santa Maria, RS, Brazil. From these three methods suggest a new one, which we call the Combined Method. This method takes into account the quality classes of eddy covariance to choose the correct method to be applied. The uncertainties of flux were obtained by the diffe...
