Solutions for Improving the Radar Refractivity Measurement by Taking Operational Constraints into Account
Publisher: American Meteorological Society
Abstract: tmospheric refractivity depends on meteorological parameters such as temperature, water vapor pressure, and air pressure and can be measured using weather radar. This could be useful for convection prediction through the ...
Empirical Estimation of Attenuation from Differential Propagation Phase Measurements at C Band
Publisher: American Meteorological Society
Abstract: A polarimetric method is devised to correct for attenuation effects at C band on reflectivity ZH and differential reflectivity ZDR measurements. An operational cross-correlation analysis is used to derive advection vectors ...
Operational Multiple-Doppler Wind Retrieval Inferred from Long-Range Radial Velocity Measurements
Publisher: American Meteorological Society
Abstract: The recent deployment of an innovative triple pulse rise time (PRT) scheme within the French operational radar network allows for the simultaneous collection of reflectivity and radial velocity measurements up to a range ...
A Fuzzy Logic Algorithm for the Separation of Precipitating from Nonprecipitating Echoes Using Polarimetric Radar Observations
Publisher: American Meteorological Society
Abstract: A fuzzy logic algorithm has been developed for the purpose of segregating precipitating from nonprecipitating echoes using polarimetric radar observations at C band. Adequate polarimetric descriptions for each type of ...
Data Quality of the Meteo-France C-Band Polarimetric Radar
Publisher: American Meteorological Society
Abstract: The French operational radar network is being upgraded and expanded from 2002 to 2006 by Meteo-France in partnership with the French Ministry of the Environment. A detailed examination of the quality of the raw polarimetric ...
Errors Caused by Long-Term Drifts of Magnetron Frequencies for Refractivity Measurement with a Radar: Theoretical Formulation and Initial Validation
Publisher: American Meteorological Society
Abstract: efractivity measurements in the boundary layer by precipitation radar could be useful for convection prediction. Until now such measurements have only been performed by coherent radars, but European weather radars are ...
Comparison of Advanced Radar Polarimetric Techniques for Operational Attenuation Correction at C Band
Publisher: American Meteorological Society
Abstract: Rain path attenuation correction is a challenging task for quantitative use of weather radar measurements at frequencies higher than S band. The proportionality relationship between specific attenuation αhh (specific ...
A Radar Simulator for High-Resolution Nonhydrostatic Models
Publisher: American Meteorological Society
Abstract: A full radar simulator for high-resolution (1?5 km) nonhydrostatic models has been developed within the research nonhydrostatic mesoscale atmospheric (Meso-NH) model. This simulator is made up of building blocks, each of ...
