Lidar technology measurements and technology: Report of panel [PDF]

open access: yes
Lidar is ready to make an important contribution to tropospheric chemistry research with a variety of spaceborne measurements that complement the measurements from passive instruments. Lidar can now be considered for near-term and far-term space missions

Developing Allometric Equations for Teak Plantations Located in the Coastal Region of Ecuador from Terrestrial Laser Scanning Data [PDF]

open access: yes, 2019
Traditional studies aimed at developing allometric models to estimate dry above-ground biomass (AGB) and other tree-level variables, such as tree stem commercial volume (TSCV) or tree stem volume (TSV), usually involves cutting down the trees.

Baseline monitoring using aircraft laser ranging [PDF]

open access: yes
The use of aircraft laser ranging for the determination of baselines between ground based retroreflectors was investigated via simulations and with tests at Wallops Flight Center using the Airborne Oceanographic Lidar (AOL) on the Wallops C-54 aircraft ...

The Lidar In-Space Technology Experiment (LITE) [PDF]

open access: yes, 1986
A spaceborne lidar system is presently being constructed for flight aboard the U. S. Space Shuttle in early 1991. The experiment, Lidar In Space Technology Experiment (LITE), utilizes a neodymium:YAG laser and 0.85 meter effective diameter Cassegranian ...

DART 3D Radiative Transfer Modeling Applied to RAMI Forests – Part 2: Lidar Waveform Simulation and Canopy Structure Analysis

open access: yesJournal of Remote Sensing
This study explores the influence of canopy structure on spaceborne Light Detection and Ranging (LiDAR) waveforms by analyzing common canopy approximations in analytical LiDAR waveform models: the omission of woody components, the use of a single leaf ...

Development of mid-infrared solid state lasers for spaceborne lidar [PDF]

open access: yes
Laser performance of Ho(3+):Tm(3+):Cr(3+):YAG crystals was investigated under both Cr:GSAG laser and flashlamp pumping. A flashlamp pumped Cr:GSAG laser was built to simulate high power quasi-CW laser diode pumping of a 2.1 micrometer holmium laser.

The Spaceborne Wind Lidar Mission ADM-Aeolus

open access: yes, 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.
