Overview of the CALIPSO Mission and CALIOP Data Processing Algorithms
David M. Winker,Mark A. Vaughan,Ali Omar,Yongxiang Hu,Kathleen A. Powell,Zhaoyan Liu,William H. Hunt,Stuart A. Young +7 more
TL;DR: Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) is a two-wavelength polarization lidar that performs global profiling of aerosols and clouds in the troposphere and lower stratosphere as discussed by the authors.
Journal ArticleDOI
THE CALIPSO MISSION: A Global 3D View of Aerosols and Clouds
David M. Winker,Jacques Pelon,James A. Coakley,Steven A. Ackerman,Robert J. Charlson,Peter R. Colarco,Pierre H. Flamant,Qiang Fu,Raymond M. Hoff,Chieko Kittaka,T. L. Kubar,H. Le Treut,M. P.

TL;DR: An in-depth overview of the architecture and performance of the SIBYL algorithm is provided, which accomplishes its goals by integrating an adaptive context-sensitive profile scanner into an iterated multiresolution spatial averaging scheme.
Journal ArticleDOI
The CALIPSO Lidar Cloud and Aerosol Discrimination: Version 2 Algorithm and Initial Assessment of Performance
Zhaoyan Liu,Mark A. Vaughan,David M. Winker,Chieko Kittaka,Brian Getzewich,Ralph Kuehn,Ali Omar,Kathleen A. Powell,Charles R. Trepte,Chris A. Hostetler +9 more
TL;DR: In this paper, the theoretical basis of the CALIPSO lidar cloud and aerosol discrimination (CAD) algorithm is reviewed and enhancements made to the version 2 algorithm that is used in the current data release (release 2).
Journal ArticleDOI
