Doppler Wind Lidar From UV to NIR: A Review With Case Study Examples

Abstract

Doppler wind lidar (DWL) uses the optical Doppler effect to measure atmospheric wind speed with high spatial-temporal resolution and long detection range and has been widely applied in scientific research and engineering applications. With the development of related technology, especially laser and detector technology, the performance of the DWL has significantly improved for the past few decades. DWL utilizes different principles and different tracers to sense the wind speed from the ground to the mesosphere, which leads to the difference in choosing the laser working wavelength. This article will review the working wavelength consideration of DWL, and typical DWLs will present from ultraviolet to near-infrared, after which three typical applications will be shown.

Optimization of Auxiliary Biaxial Receiver to Detect Blind Zone of Pulsed Coherent Wind Lidar

“…The color bar represents the goal function value. For the general MCT system as Table 1 shows, the suitable range of all the parameter sequences of the ABR system is set as Equation (16)(17)(18)(19)(20). The offset distance is still determined by…”

“…Yang et al [15] proposed to use the pseudo-phase coding technology to improve the distance resolution of the pulse CDWL system and proposed to solve the near-field blind zone problem. However the coding system has a lower magnitude of the power spectrum, compared with a non-coding system [16], so the effective detection distance of the coding system is limited. Wang [19] realizes a dual optical receiving direct detecting lidar system to solve the blind zone problem caused by the system geometry factor of the transceiver allograft.…”

An Ontology for Describing Wind Lidar Concepts

“…In recent years, measurement of wind speeds with lasers, based upon the lidar (light detection and ranging) system, has provided a modern alternative to the traditional meteorological mast instrumentation. Wind lidar makes use of the principle of optical Doppler shift between the reference radiation and radiation backscattered by aerosol particles to measure radial wind velocities at distances up to several kilometers [1][2][3][4]. In fields such as aviation, climatology, satellite-based measurements, and especially wind energy, there has been a general move towards the adoption of lidar as a cost-effective, self-contained, and adaptable solution to wind measurement.…”

Improvement of Aerosol Coarse-Mode Detection through Additional Use of Infrared Wavelengths in the Inversion of Arctic Lidar Data

“…However, recently, wind lidar systems have become a reliable tool, as they also provide aerosol backscatter profiles [28,29]. Coherent Doppler wind lidars typically operate in the near-infrared, sometimes around 1.5 µm [30]. Further, ceilometers are also used to determine backscatter profiles [31,32].…”
