Daytime convectively-driven boundary layer turbulence produces structures on scales smaller than a few kilometers that can only be resolved in modeling by large-eddy simulations (LES). We have run several LES using the Mars Regional Atmospheric Modeling System and present fits of friction velocity to a two-parameter Weibull distribution for use with lower resolution models.
