The Nonlinear Effective Attenuation Coefficient of Spaceborne Oceanic Lidar Signal [PDF]
EPJ Web of Conferences, 2020 Multiple scattering is an inevitable effect in spaceborne oceanic lidar because of the large footprint size and the high optical density of seawater. The effective attenuation coefficient klidar in oceanic lidar equation, which indicates the influence of

Pointing Verification Method for Spaceborne Lidars [PDF]
Remote Sensing, 2017 High precision acquisition of atmospheric parameters from the air or space by means of lidar requires accurate knowledge of laser pointing. Discrepancies between the assumed and actual pointing can introduce large errors due to the Doppler effect or a wrongly assumed air pressure at ground level.

Characterizing the structural complexity of the Earth's forests with spaceborne lidar. [PDF]
Nat CommunAbstract Forest structural complexity is a key element of ecosystem functioning, impacting light environments, nutrient cycling, biodiversity, and habitat quality. Addressing the need for a comprehensive global assessment we derive the first, near-global map of 3D canopy complexity using data from the GEDI spaceborne lidar mission.
