RISExponential Size Distributions of Raindrops and Vertical Air Motions Deduced from Vertically Pointing Doppler Radar Data Using a New Method
Publisher: American Meteorological Society
Abstract: Raindrop-size distributions and vertical air motions are deduced from vertically pointing C-band Doppler radar data by using a new method (described in Hauser and Amayenc, 1981) which assumes the raindrop sizes are ...
A Class of Single- and Dual-Frequency Algorithms for Rain-Rate Profiling from a Spaceborne Radar. Pad I: Principle and Tests from Numerical Simulations
Publisher: American Meteorological Society
Abstract: A class of single- and dual-frequency algorithms that can be used to infer rain-rate profile from a downward-looking spaceborne radar operating at attenuating frequencies is presented. These algorithms rely on use of ...
Retrieval of Cloud Water and Water Vapor Contents from Doppler Radar Data in a Tropical Squall Line
Publisher: American Meteorological Society
Abstract: This paper describes the retrieval of cloud water and water vapor contents from Doppler radar data. The convective part of a tropical squall line (22 June 1981) observed during the COPT 81 (Convection Profonde Tropicale ...
A New Method for Deducing Hydrometeor-Size Distributions and Vertical Air Motions from Doppler Radar Measurements at Vertical Incidence
Publisher: American Meteorological Society
Abstract: Using the hypothesis of an exponential hydrometeor-size distribution characterized by the two classical intercept (N0) and slope (?) parameters, a method is presented for simultaneously deducing N0, ? and the vertical air ...
Comparison of Rain-Profiling Methods from ARMAR Data in TOGA COARE with a View to a Possible Use with the TRMM Radar
Publisher: American Meteorological Society
Abstract: Rain measurements of the airborne Tropical Rainfall Measurement Mission (TRMM) radar simulator Airborne Rain-Mapping Radar in a typical event of Tropical Ocean and Global Atmosphere Coupled Ocean?Atmosphere Response ...
Comparison of Two Methods for the Retrieval of Thermodynamic and Microphysical Variables from Doppler Radar Measurements: Application to the Case of a Tropical Squall Line
Publisher: American Meteorological Society
Abstract: Microphysical and thermodynamic retrieval studies using a specified wind field can provide a means for analysing the different processes occurring within an observed precipitating system. Up to now, the retrieval of ...
Rainfall-Rate Retrieval from a Spaceborne Radar: Comparison between Single-Frequency, Dual-Frequency, and Dual-Beam Techniques
Publisher: American Meteorological Society
Abstract: This paper investigates the performances achievable in the retrieval of rain-rate profile from a spaceborne radar operating at attenuated frequencies. Results obtained from three radar systems using relevant range-profiling ...
Proposal for a Spaceborne Dual-Beam Rain Radar with Doppler Capability
Publisher: American Meteorological Society
Abstract: The potential characteristics and performances of a spaceborne dual-beam radar (or stereo radar) operating at 24 GHz, and devoted primarily to the retrieval of rain-rate structure by using the stereo-radar analysis, were ...
A New Optical Instrument for Simultaneous Measurement of Raindrop Diameter and Fall Speed Distributions
Publisher: American Meteorological Society
Abstract: This paper presents a recently developed optical spectro-pluviometer. The principle of the device is based upon the optical occultation of an infrared light beam by falling drops. This allows the retrieval of raindrop-size ...
