One of the surface energy balance components, the sensible heat flux, can easily be described for modelling and remote sensing purposes by means of the thermal roughness length ( zot). This roughness length is usually expressed relative to the roughness length for wind speed ( zou): kB−1 = ln(zou/zot). In the past, thekB−1 factor has been taken as a constant having a value of ca. 2 in the case of homogeneous canopies. There is some theoretical evidence that kB−1 s ould depend on friction… CONTINUE READING
