Monin–Obukhov Scale in Determining Temperature Stratification of the Surface Air Layer

The Monin–Obukhov (MO) scales estimated from experimental data received at two observation sites with different underlying surface structure under different surface air temperature stratification types are analyzed. The MO scale (its sign, first of all) is compared with current temperature profiles in the surface air layer. The MO scale sign is found to differ sometimes from actual temperature stratification, which contradicts the Monin–Obukhov similarity theory. The results can be used for refining surface air layer models which are based on this theory.
