Nine diabatic models used to describe the shape of the wind and temperature profiles in the surface boundary layer have been compared using factors common to all, such as the gradient Richardson number, the diabatic influence function, and the function psizL. Numerical integration of the models was accomplished using high-speed digital computer techniques. Experimental data used to evaluate the models were collected at locales of known surface roughness. All models are considered to be valid for a small range of stability but tend to diverge rapidly beyond the transition zone between forced and free convection. Application to data obtained at White Sands Missile Range showed that none of the models was suitable for analysis of data observed under nonstationary conditions. Author
