RISAssessment of Vertically Integrated Liquid (VIL) Water Content Radar Measurement
Publisher: American Meteorological Society
Abstract: Vertically integrated liquid (VIL) water content is a parameter obtained from a radar performing voluminal scanning. This parameter has proven useful in the detection of severe storms and may be a worthwhile indicator for ...
Identification of Vertical Profiles of Radar Reflectivity for Hydrological Applications Using an Inverse Method. Part I: Formulation
Publisher: American Meteorological Society
Abstract: The vertical variability of reflectivity in the radar beam is one of the main sources of error in estimating rainfall intensity. This vertical variability, which has several origins, is characterized globally by a function ...
Quantification 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 ...
Identification of Vertical Profiles of Reflectivity from Volume Scan Radar Data
Publisher: American Meteorological Society
Abstract: The vertical variability of reflectivity in the radar beam is an important source of error that interferes with a reliable estimation of the rainfall rate by radar. This source of error can be corrected if the vertical ...
Evaluation of RadVil, a Radar-Based Very Short-Term Rainfall Forecasting Model
Publisher: American Meteorological Society
Abstract: A very short-term rainfall forecast model is tested on actual radar data. This model, called RadVil, takes advantages of voluminal radar data through vertically integrated liquid (VIL) water content measurements. The model ...
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 ...
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 ...
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 ...
Identification of Rain-Rate Profiles from Radar Returns at Attenuating Wavelengths Using an Inverse Method: A Feasibility Study
Publisher: American Meteorological Society
Abstract: Attenuation in rainfall is recognized as one of the most significant limitations in rain-rate estimation from weather radar returns at X- or C-band wavelengths. This paper introduces a radar measurement correction as an ...
