End-to-End Simulation for a Forest-Dedicated Full-Waveform Lidar Onboard a Satellite Initialized from Airborne Ultraviolet Lidar Experiments

Remote Sensing, 2015
In order to study forests at the global scale, a detailed link budget for a lidar system onboard satellite is presented. It is based on an original approach coupling airborne lidar observations and an end-to-end simulator. The simulator is initialized by

Statistical Analysis of Simulated Spaceborne Thermodynamics Lidar Measurements in the Planetary Boundary Layer

Frontiers in Remote Sensing, 2022
The performance of a spaceborne Raman lidar offering measurements of water vapor, temperature, aerosol backscatter and extinction is assessed statistically by use of a lidar simulator and a global model to provide inputs for simulation.

Establishing a long-term cloud record from a combination of space-borne lidar observations [PDF]

EPJ Web of Conferences
This study presents a methodology to merge cloud data from different spaceborne lidar platforms, aiming to establish a long-term cloud record. By compensating for differences in wavelength, overpass time, and measurement gaps, the study reconciles data ...

Assessing Novel Lidar Modalities for Maximizing Coverage of a Spaceborne System through the Use of Diode Lasers

Remote Sensing, 2022
Current satellite lidars have sparse spatial coverage, leading to uncertainty from sampling. This complicates robust change detection and does not allow applications that require continuous coverage.

Reconciling aerosol light extinction measurements from spaceborne lidar observations and in situ measurements in the Arctic [PDF]

Atmospheric Chemistry and Physics, 2014
In this study we investigate to what degree it is possible to reconcile continuously recorded particle light extinction coefficients derived from dry in situ measurements at Zeppelin station (78.92° N, 11.85° E; 475 m above sea level), Ny-Ålesund ...
