Evapotranspiration, Hysteresis, Environmental variables


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 (Rn) at a diel timescale for a pasture area in southern Brazil. ET presents hysteresis with DPV and Temp, responding more strongly to the vapor pressure deficit.
