Abstract
The goal of this paper is to demonstrate the advantages of coupling the integrated Monin-Obukhov similarity functions with an algebraic turbulence equation to resolve the profiles of temperature and velocity in the atmospheric surface layer. The latter equation is derived using the definition of turbulent viscosity from the k-ε turbulence model. The proposed surface-layer model is validated with eddy covariance and profile measurements from the CASES99 experiment and the results are compared with classic flux-profile techniques. In doing so, the relative benefits of the presented formulation become apparent. Firstly, the addition of a turbulence model improves convergence in the moderate to very stable regime. Secondly, the addition of an extra equation allows the four atmospheric parameters of interest ( u*, θ*, L and z 0 ) to be resolved simultaneously. Furthermore, the definition of turbulent viscosity can be used to reformulate the Monin-Obukhov equations for the very stable limit.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
