Abstract
The estimation of the surface-layer parameters u * (friction velocity), θ* and q * (temperature and humidity scales), θ r and q r (temperature and humidity reference values), z o (roughness length) and d (zero-displacement) from vertical profiles of wind velocity, temperature and humidity by least-squares methods is described. The estimation is based on the flux-gradient relationships and the constant flux assumption for the transfer of momentum, sensible heat and matter near the Earth's surface.
Test calculations were carried out with the vertical profile data from the GREIV I 1974 experiment and the Great Plains Turbulence Project.
