A TKE-free method for estimating optical turbulence has been introduced which gives results as accurate as the TKE-based method described in Walters and Miller (1999) and in Miller and Walters (2001). Comparisons for simulations over the course of a year for a domain having significant orographic effects has shown the TKE-free method to be more robust, particularly in instances of (1) high wind shear near the surface at nighttime, (2) topographically induced gravity waves aloft, and (3) within the elevated daytime PBL inversion.
