Coherent Doppler lidar for measurements of wind fields

Proceedings of the IEEE, 1989
The signal-processing techniques for obtaining the velocity estimates and the fundamental factors that influence coherent lidar performance are considered. The similarities and distinctions between Doppler lidar and Doppler radars are discussed. The capability of coherent Doppler lidars for mapping wind fields over selected regions in the lower ...

Doppler Wind Lidar

2021
Wind lidars use the optical Doppler effect to measure atmospheric wind with high spatial and temporal resolution. In contrast to scalar quantities, such as temperature or humidity, the atmospheric wind is a vector quantity consisting of three components – usually referred to as vertical wind speed, horizontal wind speed, and the horizontal direction ...

Airborne Doppler lidar measurements

Applied Optics, 1986
This paper describes recent measurements using coherent Doppler lidars operating at a wavelength of 10.6 microm aboard the NASA Ames Convair 990. The purpose of the measurements was to obtain data on the atmospheric wind fields and the distribution of the backscatter coefficient at 10.6 microm. A description of the instruments is provided detailing the
