Retrieval of the turbulence parameters from spatial statistics of Doppler lidar wind estimates

We describe a technique for estimating the parameters of small-scale wind turbulence from the wind velocity measured with a pulsed solid -state- and CO2-laser-based coherent Doppler lidar. We present the algorithm for simulation of return signals of pulsed 2mkm and 10.6 mkm CDLs along with the methods for estimation of the wind turbulence parameters from the spatial structure function of wind velocity measured by CDL in the cases of both short separations between measurement points (2mkm CDL) and long ones (10.6 mkm CDL). The errors in estimation of the turbulent parameters from the lidar data are determined as functions on the signal storage time.
