CO2 laser radar for atmospheric energy measurements
Abstract
A description is given of a mobile, continuous wave Doppler CO2 lidar for the measurement of the atmospheric velocity turbulence spectrum, used in a heterodyne configuration with a 30 cm output to produce a conical scan. Fourier analysis of scan data yielded velocity power density spectra in which both the Kolmogorov -5/3 power law and departures from it were observed. The system is capable of measurement at remote sites and at a variety of altitudes, incorporating real-time data processing for versatility. It is hoped that the total energy and departures from the -5/3 power observed may prove useful in short-term meteorological forecasting.
