Scintillometry based energy fluxes compared to Bowen Ratio/Energy Balance method for evapotranspiration determination over winter wheat

Popis výsledku v původním jazyce

Evapotranspiration (ET) is an important part of water and energy balance of the ecosystems. In this paper, two different methods to determine ET are used and compared. First one is the standard and well known technique based on the measurement of air temperature and air humidity gradients called the Bowen Ratio/Energy Balance method (BREB). Second method, called scintillometery, is a relatively new technique based on detecting and evaluating of scintillations - intensity fluctuations of the signal of laser beam. Our field campaign takes place at the winter wheat field in Polkovice (the Czech Republic) in 2015. We are using a scintillometer type BLS 900 by Scintec and BREB system by EMS Brno equipped with sensors detecting net radiation, soil heat flux,air temperature and air humidity at three levels above ground, and other variables. A path length of the scintillometer is 617 m and the measurement hight is up to 2 m. The aim of this study is to compare the BREB method as an example of
