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 ...

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers
River Research and Applications, EarlyView.ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Characteristics of unique cap, Tsurushi and Hata clouds around Mount Fuji
Weather, EarlyView.Distinct clouds, such as cap clouds, Tsurushi (a type of lenticular cloud) and Hata (banner cloud‐like clouds), frequently form around Mount Fuji, an isolated peak with a slightly elliptical conical shape. Here, we examine their characteristics and occurrence patterns.

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Augmented Reality Based Doppler Lidar Data Visualization: Promises and Challenges
EPJ Web of Conferences, 2016 Augmented reality (AR) is a technology in which the enables the user to view virtual content as if it existed in real world. We are exploring the possibility of using this technology to view radial velocities or processed wind vectors from a Doppler wind

Motion compensation study for a floating Doppler wind LiDAR
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015 This paper addresses a cardanic frame as mechanical-compensation device for a Doppler-wind lidar installed on a floating sea buoy as the “moving” lidar. From the methodological point of view, the horizontal wind speed (HWS) measured by both a reference lidar (i.e., “fixed”) and a floating lidar (i.e., “moving”) with and without a cardarnic frame is ...
