Targeted Observations with an Airborne Wind Lidar [PDF]

Journal of Atmospheric and Oceanic Technology, 2005
Abstract This study investigates the possibilities and limitations of airborne Doppler lidar for adaptive observations over the Atlantic Ocean. For the first time, a scanning 2-μm Doppler lidar was applied for targeted measurements during the Atlantic “The Observing System Research and Predictability Experiment” (THORPEX) Regional ...

Airborne lidar observations of water vapor transport [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Water vapor, a minor constituent of the earth's atmosphere, plays a major role in the radiation budget and the water cycle with important implications for weather and climate. Due to the heterogeneous distribution of its sources, evaporation, and sinks, condensation and precipitation, and due to the complexity of atmospheric motion and mixing, its ...

Airborne lidar imaging of salmon [PDF]

Applied Optics, 2004
Lidar images of adult salmon are presented. The lidar system is built around a pulsed green laser and a gated intensified CCD camera. The camera gating is timed to collect light scattered from the turbid water below the fish to produce shadows in the images. Image processing increases the estimated contrast-to-noise ratio from 3.4 in the original image

Terrestrial and Airborne Lidar to Quantify Shrub Cover for Canada Lynx (Lynx canadensis) Habitat Using Machine Learning

Remote Sensing, 2023
The Canada lynx is listed as a threatened species, and as such, the identification and conservation of lynx habitats is of significant concern. Lynxes require areas with high amounts of horizontal cover made up of ground vegetation. Lidar offers a robust

Clear Waters, Stronger Depths: Advancing Bathymetric Lidar Through Community Practices [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The science of mapping beneath the water's surface with lasers is no longer novel, but its relevance has never been greater. Over the past decade, bathymetric lidar has evolved from a niche tool into a diverse ecosystem of sensors and operators, tailored

UAS Hyperspatial LiDAR Data Performance in Delineation and Classification across a Gradient of Wetland Types

Drones, 2022
Wetlands play a critical role in maintaining stable and productive ecosystems, and they continue to be at heightened risk from anthropogenic and natural degradation, especially along the rapidly developing Atlantic Coastal Plain of North America. As such,

Intercomparison of Water Vapor Data Measured with Lidar during IHOP_2002. Part II: Airborne-to-Airborne Systems [PDF]

, 2007
The dataset of the International H2O Project (IHOP_2002) gives the first opportunity for direct intercomparisons of airborne water vapor lidar systems and allows very important conclusions to be drawn for future field campaigns.
