Abstract

Estimates of the level of turbulence $C_n^2$ and the inner scale of turbulence λ₀ are obtained from measurements of the spatial covariance of laser scintillation in weak scattering conditions. Boundary layer turbulence is wide-sense nonstationary over time scales of <1 min but becomes locally wide-sense stationary on time scales of 2 min. The interpretation of the measurements is very sensitive to the form of the turbulence spectrum in the dissipation region.
