RISQuantification of Path-Integrated Attenuation for X- and C-Band Weather Radar Systems Operating in Mediterranean Heavy Rainfall
Publisher: American Meteorological Society
Abstract: The aim of the current study is to quantify attenuation effects that X- and C-band weather radar systems may experience in heavy rainfall. Part of this information can be obtained from power-law relationships between the ...
Attenuation in Rain for X- and C-Band Weather Radar Systems: Sensitivity with respect to the Drop Size Distribution
Publisher: American Meteorological Society
Abstract: This paper is devoted to a sensitivity study of the equation describing attenuation effects in rain for ground-based weather radar systems operating at X- or C-band wavelengths. First, the so-called attenuation equation, ...
Simulation of Radar Mountain Returns Using a Digitized Terrain Model
Publisher: American Meteorological Society
Abstract: The aim of the present study is to characterize mountain returns measured with a ground-based weather radar operating in a mountainous region. A computation code based on the use of a digitized terrain model is developed ...
Identification of Vertical Profiles of Reflectivity for Correction of Volumetric Radar Data Using Rainfall Classification
Publisher: American Meteorological Society
Abstract: Nonuniform beam filling associated with the vertical variation of atmospheric reflectivity is an important source of error in the estimation of rainfall rates by radar. It is, however, possible to correct for this error ...
Unified Formulation of Single- and Multimoment Normalizations of the Raindrop Size Distribution Based on the Gamma Probability Density Function
Publisher: American Meteorological Society
Abstract: his study offers a unified formulation of single- and multimoment normalizations of the raindrop size distribution (DSD), which have been proposed in the framework of scaling analyses in the literature. The key point is ...
A Physically Based Identification of Vertical Profiles of Reflectivity from Volume Scan Radar Data
Publisher: American Meteorological Society
Abstract: he vertical profile of reflectivity (VPR) must be identified to correct estimations of rainfall rates by radar for the nonuniform beam filling associated with the vertical variation of radar reflectivity. A method for ...
Rain Measurement in Hilly Terrain with X-Band Weather Radar Systems: Accuracy of Path-Integrated Attenuation Estimates Derived from Mountain Returns
Publisher: American Meteorological Society
Abstract: The authors recently showed that when attenuating wavelengths are used mountain returns may allow estimation of path-integrated attenuations (PIAs) between a ground-based weather radar and a given mountain, an application ...
Influence of the Vertical Profile of Reflectivity on Radar-Estimated Rain Rates at Short Time Steps
Publisher: American Meteorological Society
Abstract: The present study aims to demonstrate the major influence of the vertical heterogeneity of rainfall on radar?rain gauge assessment. For this purpose, an experimental setup was deployed during the HYDROMET Integrated Radar ...
Hydrologic Visibility of Weather Radar Systems Operating in Mountainous Regions: Case Study for the Ardèche Catchment (France)
Publisher: American Meteorological Society
Abstract: A simulation procedure has been developed for use in predetermining the expected quality of rain-rate estimates that a given weather radar system operating in a mountainous region may obtain over a given hydrologic catchment. ...
Bollène-2002 Experiment: Radar Quantitative Precipitation Estimation in the Cévennes–Vivarais Region, France
Publisher: American Meteorological Society
Abstract: The Bollène-2002 Experiment was aimed at developing the use of a radar volume-scanning strategy for conducting radar rainfall estimations in the mountainous regions of France. A developmental radar processing system, called ...
