Abstract

An optical technique is described that determines the path-averaged value of a refractive-index structure parameter at 10.6 µm by use of a pulsed coherent CO2 lidar in direct detection and hard-target returns. The lidar measurements are compared with measurements taken by a 0.9-µm scintillometer and temperature probe (with humidity corrections). The experimental results show good agreement for C n 2 ≥ 10-14 m-2/3. With respect to practical applications the new technique permits C n 2 lidar measurements in a neutral meteorological situation to an unstably stratified convective boundary layer over long ranges (1 km or more).
