Exponential-linear stability correction functions for weak to moderate instability near the ground

Stability correction functions which combine the exponent of z/L, and a linear term in z/L, are proposed for the unstable case. The functions provide a reasonably close fit to the _m and _h results of Dyer and Hicks (1970) for 0 < –z/L 1, but they cannot be extended to cases of strong instability. Attractive features are the ability to integrate the expressions directly in terms of z/L, and a particularly close fit of the integrated result to experimentally derived _m values.
