“…Since then, several methods for ground-based lidar measurements of wind using molecular backscattering have been proposed and demonstrated (Bills et al, 1991;Abreu et al, 1992;Tepley et al, 1994;Rees et al, 1996;S. M. Khaykin et al: Doppler lidar at Observatoire de Haute-Provence Friedman et al, 1997;Gentry et al, 2000;Yan et al, 2017). The direct-detection technique for wind profiling has been successfully realized in an airborne Doppler lidar -A2D, Aeolus Airborne Demonstrator (Reitebuch et al, 2009).…”

Abstract. A direct-detection Rayleigh–Mie Doppler lidar for measuring horizontal wind speed in the middle atmosphere (10 to 50 km altitude) has been deployed at Observatoire de Haute-Provence (OHP) in southern France starting from 1993. After a recent upgrade, the instrument gained the capacity of wind profiling between 5 and 75 km altitude with vertical resolution up to 115 m and temporal resolution up to 5 min. The lidar comprises a monomode Nd:Yag laser emitting at 532 nm, three telescope assemblies and a double-edge Fabry–Pérot interferometer for detection of the Doppler shift in the backscattered light. In this article, we describe the instrument design, recap retrieval methodology and provide an updated error estimate for horizontal wind. The evaluation of the wind lidar performance is done using a series of 12 time-coordinated radiosoundings conducted at OHP. A point-by-point intercomparison shows a remarkably small average bias of 0.1 m s−1 between the lidar and the radiosonde wind profiles with a standard deviation of 2.3 m s−1. We report examples of a weekly and an hourly observation series, reflecting various dynamical events in the middle atmosphere, such as a sudden stratospheric warming event in January 2019 and an occurrence of a stationary gravity wave, generated by the flow over the Alps. A qualitative comparison between the wind profiles from the lidar and the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecast System is also discussed. Finally, we present an example of early validation of the European Space Agency (ESA) Aeolus space-borne wind lidar using its ground-based predecessor.

“…Based on the favorable character of laser, Rayleigh lidar has the advantages of high time-space resolution, high detection accuracy, and good flexibility. Rayleigh lidar has been successfully equipped on vehicles [2], ships [3], airplanes [4], and balloons [5]. Compared to ground-based and shipborne lidars, the attenuation of the laser beam and its backscattered signal in the atmosphere is smaller, leading to higher quality of the lidar signal when equipped on floating platforms (airplanes and balloons).…”

“…Modern Doppler lidar systems have exploited developments in fiber optics to address a need for compact and accurate instruments that are more easily deployed and cost effective. Though there are commercial systems available (Pearson et al 2009;Wächter et al 2008), many groups are still conducting research on these systems to minimize their volume, maximize their sensitivity, and increase resolved range (Xia et al 2017;Yan et al 2017;Abari et al 2014;Wang et al 2017Wang et al , 2019b. This paper will address a recent push to advance lidar measurements by developing a compact, near-infrared, pulsed Doppler lidar built almost entirely with robust, telecommunications grade equipment that allows rapid and motion stabilized field deployments.…”

This work details a master oscillator power amplifier (MOPA) microjoule-class pulsed coherent Doppler lidar system configuration designed to measure line-of-sight wind velocities and backscatter intensity of atmospheric aerosols. The instrument is unique in its form factor. It consists of two physically separated modules connected by a 10 m umbilical cable. One module hosts the transceiver, which is composed of the telescope, transmit/receive (T/R) switch, and high-gain optical amplifier, and is housed in a small box (34.3 cm × 34.3 cm × 17.8 cm). The second module contains the data acquisition system and several electro-optical components. This form factor enables deployments on platforms that are otherwise inaccessible by commercial and research instruments of similar design. In this work, optical, electrical, and data acquisition components and configurations of the lidar are detailed and two example deployments are presented. The first deployment describes measurements of a controlled wildfire burn from a small aircraft to measure vertical plume dynamics and fire inflow conditions during summer in Florida. The second presents measurements of the marine boundary layer height and vertical velocity and variance profiles from the Research Vessel (R/V) Thomas Thompson. The new instrument has enabled greater flexibility in field campaigns where previous instruments would have been too costly or space prohibitive to deploy.
