Turbulence Detection in the Atmospheric Boundary Layer Using Coherent Doppler Wind Lidar and Microwave Radiometer

The refractive index structure constant (Cn2) is a key parameter used in describing the influence of turbulence on laser transmissions atmosphere. Three different methods for estimating Cn2 were analyzed detail. A new method that uses combination these continuous profiling with both high temporal and spatial resolution proposed demonstrated. Under assumption Kolmogorov “2/3 law”, profile can be calculated by using wind field turbulent kinetic energy dissipation rate (TKEDR) measured coherent Doppler lidar (CDWL) other meteorological parameters derived from microwave radiometer (MWR). In horizontal experiment, comparison between results our measurements made large aperture scintillometer (LAS) conducted. correlation coefficient, mean error, standard deviation them six-day observation are 0.8073, 8.18 × 10−16 m−2/3 1.27 10−15 m−2/3, respectively. vertical direction, atmospheric boundary layer (ABL) retrieved. addition, limitation uncertainty this under circumstances analyzed, which shows relative error estimation normally does not exceed 30% convective (CBL).
