The Airborne Demonstrator for the Direct-Detection Doppler Wind Lidar ALADIN on ADM-Aeolus. Part I: Instrument Design and Comparison to Satellite Instrument

TLDR
In this article, the European Space Agency (ESA) decided to implement a Doppler wind lidar mission called the Atmospheric Dynamics Mission Aeolus (ADM-Aeolus) to demonstrate the potential of the doppler lidar technology and the expected impact on numerical weather forecasting.
Abstract
The global observation of profiles of the atmospheric wind speed is the highest-priority unmet need for global numerical weather prediction. Satellite Doppler lidar is the most promising candidate to meet the requirements on global wind profile observations with high vertical resolution, precision, and accuracy. The European Space Agency (ESA) decided to implement a Doppler wind lidar mission called the Atmospheric Dynamics Mission Aeolus (ADM-Aeolus) to demonstrate the potential of the Doppler lidar technology and the expected impact on numerical weather forecasting. An airborne prototype of the instrument on ADM-Aeolus was developed to validate the instrument concept and retrieval algorithms with realistic atmospheric observations before the satellite launch. It is the first airborne direct-detection Doppler lidar for atmospheric observations, and it is operating at an ultraviolet wavelength of 355 nm. The optical design is described in detail, including the single-frequency pulsed laser and th...

The North Atlantic Waveguide and Downstream Impact Experiment

TL;DR: The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) explored the impact of diabatic processes on disturbances of the jet stream and their influence on downstream high-impact weather through the deployment of four research aircraft, each with a sophisticated set of remote-sensing and in situ instruments, and coordinated with a suite of ground-based measurements as discussed by the authors.

The Spaceborne Wind Lidar Mission ADM-Aeolus

TL;DR: In this paper, a Doppler wind lidar mission named Atmospheric Dynamics Mission ADM-Aeolus is proposed to provide vertical profiles from ground up to the lower stratosphere of one component of the horizontal wind vector, which is perpendicular to the flight track.

Measurement of Aerosol Motion and Wind Velocity in the Lower Troposphere by Doppler Optical Radar

TL;DR: An optical radar has been used to measure the radial wind velocity component in the lower troposphere by detecting interferometrically the bulk Doppler shift affecting the echoes from atmospheric aerosols as discussed by the authors.

Theory of the double-edge technique for Doppler lidar wind measurement

TL;DR: A method that allows the Rayleigh and aerosol components of the signal to be independently determined and the correction process does not significantly increase the measurement noise for Rayleigh-to-aerosol ratios as high as 10.5 m/s is described.

The Double Edge Technique for Doppler lidar wind measurement

TL;DR: In this paper, the edge measurement is made as a differential frequency measurement between the outgoing laser signal and the atmospheric backscattered return for each pulse, and the measurement is insensitive to laser and edge filter frequency jitter and drift at a level less than a few parts in 10(exp 10).

Targeted Observations with an Airborne Wind Lidar

TL;DR: In this article, the possibilities and limitations of airborne Doppler lidar for adaptive observations over the Atlantic Ocean were investigated for the first time, and a scanning 2-μm DoP was applied for targeted measurements during the Atlantic "The Observing System Research and Predictability Experiment" (THORPEX) Regional Campaign (A-TReC) in November and December 2003.
