The Doppler Lidar for Atmospheric Wind Observation

Coherent Doppler lidar for wind farm characterization

Coherent Doppler lidar measurements are of increasing interest for the wind energy industry. Wind measurements are fundamental inputs for the evaluation of potential energy yield and performance of wind farms. Three-dimensional scanning Doppler lidar may provide a new basis for wind farm site selection, design and optimization. In this paper, the authors discuss Doppler lidar measurements obtai...

Micro-pulse upconversion Doppler lidar for wind and visibility detection in the atmospheric boundary layer.

For the first time, to the best of our knowledge, a compact, eye-safe, and versatile direct detection Doppler lidar is developed using an upconversion single-photon detection method at 1.5 μm. An all-fiber and polarization maintaining architecture is realized to guarantee the high optical coupling efficiency and the robust stability. Using integrated-optic components, the conservation of etendu...

Impact Assessment of a Doppler Wind Lidar in Space on Atmospheric Analyses and Numerical Weather Prediction

Wind profiles from space would help to fill in data sparse areas over the oceans, the tropics, and the southern hemisphere. ESA has conducted a phase A study for the Earth Explorer Atmospheric Dynamics Mission (ADM). A polar satellite with a Doppler Wind Lidar (DWL) on board is proposed for this mission and which is described in this session by Ingmann. The DWL measures wind profiles in the tro...

Analysis on wind retrieval methods for Rayleigh Doppler lidar

Wind Retrieval Algorithms for the Wind Products of the Airborne Coherent Doppler Lidar

The airborne coherent Doppler lidar could provide the wind velocity relative to the motion of the lidar. The retrieval algorithms are complex corresponding to Ground-based lidar, due to the Doppler shift caused by mobile platform. This article gives a thorough analysis of the wind retrieval algorithms for the wind products of airborne Doppler lidar, include the correction for the lidar velocity...
