Evaluating the Uncertainties in Forest Canopy Height Measurements Using ICESat-2 Data

Journal of Remote Sensing
Forest ecosystems have been identified as major carbon stocks in terrestrial ecosystems; therefore, their monitoring is critical. Forests cover large areas, making it difficult to monitor and maintain up-to-date information.

The Spaceborne Wind Lidar Mission ADM-Aeolus

, 2012
Measurements of winds throughout the atmosphere are crucial for both numerical weather prediction and for climate studies. Nevertheless, observations of height profiles of the global wind field are lacking. Thus the European Space Agency decided to establish a Doppler wind lidar mission named Atmospheric Dynamics Mission ADM-Aeolus.

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.
