Cloud ice: A climate model challenge with signs and expectations of progress
Duane E. Waliser,J.-L. F. Li,Christopher P. Woods,Richard T. Austin,Julio T. Bacmeister,Jiun-Dar Chern,Anthony D. Del Genio,Jonathan H. Jiang,Zhiming Kuang,Huan Meng,Patrick Minnis,Steve Platnick,William B. Rossow,William B. Rossow,Graeme L. Stephens,S. Sun-Mack,Wei-Kuo Tao,Adrian M. Tompkins,Adrian M. Tompkins,Deborah G. Vane,Christopher J. Walker,Dong Wu +21 more
TL;DR: In this article, the authors illustrate the shortcomings evident in model representations of cloud ice through a comparison of the simulations assessed in the Intergovernmental Panel on Climate Change Fourth Assessment Report, briefly discuss the range of global observational resources that are available, and describe the essential components of the model parameterizations that characterize their "cloud" ice and related fields.
Journal ArticleDOI
Airborne spectral measurements of surface-atmosphere anisotropy for several surfaces and ecosystems over southern Africa
Charles K. Gatebe,Charles K. Gatebe,Michael D. King,Steve Platnick,G. Thomas Arnold,G. Thomas Arnold,Eric Vermote,Beat Schmid +7 more
TL;DR: In this article, the authors present results of BRDF measurements taken over two Earth Observing System (EOS) validation sites: Skukuza tower, South Africa (25.0°S, 31.5°E) and Mongu tower, Zambia (15.4°S and 23.3°E).
Journal ArticleDOI
Remote sensing of cloud top pressure/height from SEVIRI: analysis of ten current retrieval algorithms
Ulrich Hamann,Ulrich Hamann,Andi Walther,Bryan A. Baum,Ralf Bennartz,Ralf Bennartz,Luca Bugliaro,M. Derrien,Peter N. Francis,Andrew K. Heidinger,S. Joro,Anke Kniffka,H. Le Gleau,M. Lockhoff,H.-J. Lutz,Jan Fokke Meirink,Patrick Minnis,R. Palikonda,R. A. Roebeling,Anke Thoss,Steve Platnick,P. Watts,G. Wind +22 more
TL;DR: In this paper, the authors compared the performance of the SEVIRI cloud top pressure (CTP) data sets with each other, and found that the average CTHs derived by the SeveIRI algorithms are closer to the Cloud Profiling Radar (CPR) than to CALIOP measurements.
Journal ArticleDOI
Satellites See the World’s Atmosphere
Steven A. Ackerman,Steven A. Ackerman,Steve Platnick,P. K. Bhartia,Bryan N. Duncan,Tristan L'Ecuyer,Tristan L'Ecuyer,Andrew K. Heidinger,Gail Skofronick-Jackson,Norman G. Loeb,Timothy J. Schmit,N. Smith +11 more
TL;DR: Satellite meteorology is a relatively new branch of the atmospheric sciences as discussed by the authors, which emerged in the late 1950s during the Cold War and built on the advances in rocketry after World War I.
Journal ArticleDOI
A framework based on 2‐D Taylor expansion for quantifying the impacts of subpixel reflectance variance and covariance on cloud optical thickness and effective radius retrievals based on the bispectral method
Zhibo Zhang,Frank Werner,H. M. Cho,H. M. Cho,G. Wind,Steve Platnick,Andrew S. Ackerman,L. Di Girolamo,Alexander Marshak,Kerry Meyer,Kerry Meyer +10 more
TL;DR: This framework provides a mathematical explanation of how the sub-pixel variation in VIS/NIR band influences the r e retrieval and why it can sometimes outweigh the influence of variations in the SWIR band and dominate the error in r e retrievals, leading to a potential contribution of positive bias to the r E retrieval.
