Lidar observations of cirrus clouds in Palau (7°33? N, 134°48? E)

A sub-tropical cirrus clouds climatology from Reunion Island (21°S, 55°E) lidar data set

Comparison of In-situ Balloon-borne and Lidar Measurement of Cirrus Clouds

A series of in-situ balloon-borne experiments conducted at Kiruna, Sweden (68 °N), is studying uppertropospheric, cold ice clouds in arctic latitudes. Experiments are launched from Esrange Space Center and collect ice particles with an in-situ imaging instrument. One of the aims with these measurements is to improve satellite remote sensing of cold ice clouds. Such clouds can be observed by lid...

Classification of particle effective shape ratios in cirrus clouds based on the lidar depolarization ratio.

A shape classification technique for cirrus clouds that could be applied to future spaceborne lidars is presented. A ray-tracing code has been developed to simulate backscattered and depolarized lidar signals from cirrus clouds made of hexagonal-based crystals with various compositions and optical depth, taking into account multiple scattering. This code was used first to study the sensitivity ...

First observations of noctilucent clouds by lidar at Svalbard, 78 N

In summer 2001 a potassium lidar was installed near Longyearbyen (78 N) on the north polar island of Spitsbergen which is part of the archipelago Svalbard. At the same place a series of meteorological rockets (“falling spheres”, FS) were launched which gave temperatures from the lower thermosphere to the stratosphere. The potassium lidar is capable of detecting noctilucent clouds (NLCs) and of ...

Backscatter Color Ratios of Cirrus Clouds Measured by the Cloud Physics Lidar

The Cloud Physics Lidar (CPL) is a threewavelength, polarization-sensitive elastic backscatter lidar that flies aboard NASA’s high-altitude ER2 research aircraft. This work presents spatial and optical analyses of the combined cirrus cloud measurements acquired by CPL during eight separate field campaigns occurring from 2002 to 2007. Particular attention is given to the retrieval and characteri...
