Detecting Features in Spaceborne Backscatter Lidar Data: Spatial Averaging vs. Machine Learning Based Denoising [PDF]

EPJ Web of Conferences
Space-based lidar systems provide critical information about the vertical distributions of clouds and aerosols that greatly improve our understanding of the climate system. However, daytime spaceborne lidar signals are degraded by solar background.

Assessment of terrain elevation estimates from ICESat-2 and GEDI spaceborne LiDAR missions across different land cover and forest types

Science of Remote Sensing, 2022
Accurate measurements of terrain elevation are crucial for many ecological applications. In this study, we sought to assess new global three-dimensional Earth observation data acquired by the spaceborne Light Detection and Ranging (LiDAR) missions Ice ...

Regional Scale Rain-Forest Height Mapping Using Regression-Kriging of Spaceborne and Airborne LiDAR Data: Application on French Guiana

Remote Sensing, 2016
LiDAR data has been successfully used to estimate forest parameters such as canopy heights and biomass. Major limitation of LiDAR systems (airborne and spaceborne) arises from their limited spatial coverage.

Performance Evaluation of Spaceborne Integrated Path Differential Absorption Lidar for Carbon Dioxide Detection at 1572 nm

Remote Sensing, 2020
As one of the most influential greenhouse gases, carbon dioxide (CO2) has a profound impact on the global climate. The spaceborne integrated path differential absorption (IPDA) lidar will be a great sensor to obtain the columnar concentration of CO2 with

Performance evaluation of spaceborne oceanographic lidar for optical properties detection in global ocean [PDF]

EPJ Web of Conferences
Detection of vertical distribution of optical properties in global ocean is of high priority to the study of marine environment and carbon cycle. Lidar has the advantage of measuring profiles of optical properties in the water. In this paper, in order to

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

On-Orbit Calibration for Spaceborne Line Array Camera and LiDAR

Remote Sensing, 2022
For a multi-mode Earth observation satellite carrying a line array camera and a multi-beam line array LiDAR, the relative installation attitude of the two sensors is of great significance. In this paper, we propose an on-orbit calibration method for the relative installation attitude of the camera and the LiDAR with no need for the calibration field ...
