Journal ArticleDOI
Systematic variation of drop size and radar-rainfall relations
TL;DR: In this article, time histories of the characteristics of the drop size distribution of surface disdrometer measurements collected at Kapingamarangi Atoll were partitioned for several storms using rain rate R, reflectivity factor Z, and median diameter of the distribution of water content D0.
Journal ArticleDOI
Developments in UHF lower tropospheric wind profiling at NOAA's Aeronomy Laboratory
D. A. Carter,Kenneth S. Gage,Warner L. Ecklund,Wayne M. Angevine,Paul E. Johnston,A. C. Riddle,J. S. Wilson,Christopher R. Williams +7 more
TL;DR: An overview of the architecture of the UHF profiler system as it has evolved over the past decade including the development of radio acoustic sounding system (RASS) capabilities is presented in this paper.
Journal ArticleDOI
Classification of Precipitating Clouds in the Tropics Using 915-MHz Wind Profilers
TL;DR: In this paper, an algorithm was developed that classifies precipitating clouds into either stratiform, mixed stratiform/convective, deep convective, or shallow convective clouds by analyzing the vertical structure of reflectivity, velocity, and spectral width derived from measurements made with the vertical beam of a 915-MHz Doppler wind profiler.
Journal ArticleDOI
Using Dual-Polarized Radar and Dual-Frequency Profiler for DSD Characterization: A Case Study from Darwin, Australia
TL;DR: In this paper, the authors compare the reflectivity Z, median volume diameter D0, and rain rate R from a dual-frequency profiler and the C-band polarimetric radar (C-POL), which are both located near Darwin, Australia.
Journal ArticleDOI
The Midlatitude Continental Convective Clouds Experiment (MC3E)
Michael Jensen,Walter A. Petersen,Aaron Bansemer,Nitin Bharadwaj,Lawrence D. Carey,Daniel J. Cecil,Scott Collis,A. D. Del Genio,Brenda Dolan,J. Gerlach,Scott E. Giangrande,Andrew J. Heymsfield,Gerald M. Heymsfield,Pavlos Kollias,Timothy J. Lang,Stephen W. Nesbitt,Andrea Neumann,Michael R. Poellot,Steven A. Rutledge,Mathew R. Schwaller,Ali Tokay,Christopher R. Williams,David B. Wolff,Shaocheng Xie,Edward J. Zipser +24 more
TL;DR: A variety of cloud and precipitation events were sampled during MC3E, of which results from three deep convective events are highlighted, and vertical structure, air motions, precipitation drop size distributions, and ice properties were retrieved from multiwavelength radar, profiler, and aircraft observations.
