Horizontal structure function and vertical correlation analysis of mesoscale water vapor variability observed by airborne lidar [PDF]

, 2013
Analysis is presented of airborne lidar measurements of water vapor, covering a height range from 1.5 to 10.4 km, from three field campaigns (midlatitude summer, polar winter, and subtropical summer).

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

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.

Latent Heat Flux Profiles from Collocated Airborne Water Vapor and Wind Lidars during IHOP_2002 [PDF]

, 2007
Latent heat flux profiles in the convective boundary layer (CBL) are obtained for the first time with the combination of the DLR water vapor differential absorption lidar (DIAL) and the NOAA high resolution Doppler wind lidar (HRDL).

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Airborne lidar observations supporting the ADM-Aeolus mission for global wind profiling [PDF]

, 2012
The Atmospheric Dynamics Mission ADM-Aeolus of ESA will be the first lidar mission to sense the global wind field from space. The instrument is based on a direct-detection Doppler lidar operating at 354.9 nm with two spectrometers for aerosol/cloud ...

Spaceborne Reflector SAR Systems with Digital Beamforming [PDF]

, 2012
Spaceborne Synthetic Aperture Radar (SAR) imaging enters an era where increasingly short revisit times, or large swath widths, respectively, and high spatial resolutions are requested.

Effects of solar activity on noise in CALIOP profiles above the South Atlantic Anomaly [PDF]

Atmospheric Measurement Techniques, 2014
We show that nighttime dark noise measurements from the spaceborne lidar CALIOP contain valuable information about the evolution of upwelling high-energy radiation levels.
