Abstract

The ground-based coherent lidar developped at LMD has been upgraded to make it more practical for atmospheric measurements. One experimental difficulty with our system is the time spent prior any backscatter or wind measurement for optical alignment, frequency offset tuning and stabilization. The overall procedure has to be repeated every time an experiment is to be conducted. The main modifications implemented last year deal with the TE-CO2 transmitter, the local oscillator, and a CCD camera to look at the remote targets we are aiming at for alignment or calibration purposes.
