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

TL;DR: In this paper, a multispectral expert system used a neural network approach to provide Rapid Response thickness class maps using a spectral library approach based on the shape and depth of near infrared spectral absorption features.
Journal ArticleDOI
An Accurate Parameterization of the Radiative Properties of Water Clouds Suitable for Use in Climate Models
Yongxiang Hu,Knut Stamnes +1 more
TL;DR: In this article, a new parameterization of the radiative properties of water clouds is presented, based on the Mie theory, for both solar and terrestrial spectra and for cloud equivalent radii in the range 2.5-60 µm.
Proceedings ArticleDOI
Fully automated analysis of space-based lidar data: an overview of the CALIPSO retrieval algorithms and data products
Mark A. Vaughan,Stuart A. Young,David M. Winker,Kathleen A. Powell,Ali Omar,Zhaoyan Liu,Zhaoyan Liu,Yongxiang Hu,Chris A. Hostetler +8 more
TL;DR: An integrated analysis scheme that employs a nested, multi-grid averaging technique designed to optimize tradeoffs between spatial resolution and signal-to-noise ratio is described.
