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.
