A novel spaceborne lidar calibration technique: the multi-calibration lidar experiment [PDF]

International Conference on Space Optics — ICSO 2006, 2017
Although the noticeable progress achieved by ground-based lidars, using lidars as an operational spaceborne i nstruments still poses issu es to be solved. A key issue is the long-term stability of the instrument over the mission lifetime, as a whole as well as at the level of each subsystem; another important issue is related to the processes of ...

Spaceborne LIDAR systems and their usage: A review

Turkish Journal of Remote Sensing
LIDAR (Light Detection and Ranging) systems are technologies that use laser beams to measure surface topography with high precision. Spaceborne LIDAR systems enable multidisciplinary research thanks to the unique properties of laser technology. This review examined 87 Turkish and English sources including articles, conference papers, theses, official ...

Spaceborne remote sensing effectively maps species richness across taxonomic groups in a mountain landscape

International Journal of Applied Earth Observations and Geoinformation
Biodiversity decline due to global change poses a pressing challenge for conservation efforts worldwide. To improve the efficiency of conservation projects, spatially explicit information on species richness is needed, yet this information is challenging

Global Elevation Inversion for Multiband Spaceborne Lidar: Predevelopment of Forest Canopy Height

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Compared to single-band spaceborne lidars such as the global ecosystem dynamics investigation (GEDI) and Ice, Cloud and Land Elevation Satellite-2 (ICESat-2), multiband spaceborne lidars improve the detection of the canopy and ground.

Comparison of Cirrus Cloud Characteristics as Estimated by A Micropulse Ground-Based Lidar and A Spaceborne Lidar CALIOP Datasets Over Lille, France (50.60 °N, 3.14 ° E)

EPJ Web of Conferences, 2016
Our goal is to establish a climatology of cirrus cloud properties over Lille, France (50.60°N, 3.14 °E) using a ground-based lidar. A statistical analysis of mid-latitude cirrus clouds from lidar data in Lille over the period 2008-2013 is presented and ...

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.
