Scan strategies for wind profiling with Doppler lidar – an large-eddy simulation (LES)-based evaluation [PDF]

Atmospheric Measurement Techniques, 2022
Doppler-lidar scan techniques for wind profiling rely on the assumption of a horizontally homogeneous wind field and stationarity for the duration of the scan.

Monitoring Dust Events Using Doppler Lidar and Ceilometer in Iceland

Atmosphere, 2020
Ground-based lidars and ceilometers are widely used for dust and volcanic ash observation around the world. This is particularly interesting in Iceland where high-altitude dust events occur frequently during strong wind conditions and volcanic eruptions.

Latent Heat Flux Profiles from Collocated Airborne Water Vapor and Wind Lidars during IHOP_2002 [PDF]

, 2007
Latent heat flux profiles in the convective boundary layer (CBL) are obtained for the first time with the combination of the DLR water vapor differential absorption lidar (DIAL) and the NOAA high resolution Doppler wind lidar (HRDL).
