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 ...

Quantifying Discrepancies Between Spaceborne and Ground-Based Lidar Aerosol Vertical Profiles over Coastal Sea–Land Transition Zones

Remote Sensing
Accurate validation of spaceborne lidar data is fundamental for reliable quantification of aerosol vertical distributions, which strongly influence air quality and climate effects.

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.

An improved geolocation methodology for spaceborne radar and lidar systems

Atmospheric Measurement Techniques
Abstract. Geolocation and co-registration methodologies are essential for the accurate interpretation of observations from spaceborne remote sensors. In preparations for the Earth Cloud Aerosol and Radiation Explorer (EarthCARE), here, we refine the definition of these techniques and present various examples of geolocation assessments.
