Abstract

The boundary layer of the atmosphere (BLA) is the space above the Earth, properties of which are strongly influenced by the Earth surface. Water vapor evaporating from the surface is transported in the BLA; therefore, the properties of the BLA can strongly influence the evapotranspiration process. Vertical distributions of the meteorological characteristics (wind, air humidity, and air temperature profiles) in this layer are described quantitatively. Parameters of those profiles as well as methods of their evaluation are presented. Parameters of the evaporating surface (roughness length, zero displacement level) are described as well as methods of their estimation. Transport properties of the BLA are of primary importance and can be expressed by transport coefficients. Methods of heat and water vapor transport coefficients estimation in the BLA are described. The influence of the state of an atmosphere on transport coefficients is discussed and the method of its quantification is given.
