High resolution Doppler lidar [PDF]

A high resolution lidar system was implemented to measure winds in the lower atmosphere. The wind speed along the line of sight was determined by measuring the Doppler shift of the aerosol backscattered laser signal.

Evaluation of TanDEM-X DEMs on selected Brazilian sites: comparison with SRTM, ASTER GDEM and ALOS AW3D30

, 2018
A first assessment of the TanDEM-X DEMs over Brazilian territory is presented through a comparison with SRTM, ASTER GDEM and ALOS AW3D30 DEMs in seven study areas with distinct geomorphological contexts, vegetation coverage and land use.

Simulation and assessment of spaceborne hybrid Doppler wind lidar, part 1: the spaceborne two-beam stepping direct detection Doppler wind lidar

Optics Express
Accurately measuring wind fields is crucial for weather forecasting, climate and meteorological research, aeronautical flights, and wind resource exploitation. Spaceborne Doppler wind lidar has become an important instrument for observing the vertical profile of the global wind field, with the successful operation of Aeolus.

A Spaceborne Wind Sounder Lidar (SBL)

, 1998
This paper presents a commercial oriented SpaceBorne wind sounder LIDAR (SBL) system, which is designed for advanced remote sensing purposes. The main objectives of SBL are the measurement of wind velocities, by measuring its Doppler shifted reflection from the various atmospheric layers.

Airborne lidar observations supporting the ADM-Aeolus mission for global wind profiling [PDF]

, 2012
The Atmospheric Dynamics Mission ADM-Aeolus of ESA will be the first lidar mission to sense the global wind field from space. The instrument is based on a direct-detection Doppler lidar operating at 354.9 nm with two spectrometers for aerosol/cloud ...

Concept of a Dual-Spaceborne Doppler Lidar System for Global Wind Measurement

Remote Sensing
The scarcity of global wind field data limits the accuracy of numerical weather prediction. The currently operational spaceborne Doppler lidar (the European Space Agency’s Aeolus) measures only a single line-of-sight (LOS) wind component, which leads to ...
