MANDOP Analysis over Complex Orography in the Context of the MAP Experiment
Publisher: American Meteorological Society
Abstract: The present paper deals with the adaptation of the Multiple Analytical Doppler (MANDOP) analysis to Doppler radar observations over complex orography. The objective, in the context of the Mesoscale Alpine Programme (MAP), ...
The New French Operational Polarimetric Radar Rainfall Rate Product
Publisher: American Meteorological Society
Abstract: n 2012 the Météo France metropolitan operational radar network consists of 24 radars operating at C and S bands. In addition, a network of four X-band gap-filler radars is being deployed in the French Alps. The network ...
Influence of Ground Clutter Contamination on Polarimetric Radar Parameters
Publisher: American Meteorological Society
Abstract: The influence of ground clutter contamination on the estimation of polarimetric radar parameters, horizontal reflectivity (Zh), differential reflectivity (Zdr), correlation coefficient (?h?), and differential propagation ...
Real-Time Retrieval of the Wind from Aliased Velocities Measured by Doppler Radars
Publisher: American Meteorological Society
Abstract: Doppler radar measurements provide the radial wind within an unambiguous interval due to the limited value of the sampling frequency (pulse repetition frequency). Many algorithms have been developed to retrieve true wind ...
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 ...
Operational Monitoring of Radar Differential Reflectivity Using the Sun
Publisher: American Meteorological Society
Abstract: A method for the daily monitoring of the differential reflectivity bias for polarimetric weather radars is presented. Sun signals detected in polar volume data produced during operational scanning of the radar are used. ...
Absolute Calibration of Radar Reflectivity Using Redundancy of the Polarization Observations and Implied Constraints on Drop Shapes
Publisher: American Meteorological Society
Abstract: A major limitation of improved radar-based rainfall estimation is accurate calibration of radar reflectivity. In this paper, the authors fully automate a polarimetric method that uses the consistency between radar reflectivity, ...
X-Band Polarimetric Weather Radar Observations of a Hailstorm
Publisher: American Meteorological Society
Abstract: his paper presents an analysis of a hail event that occurred 27 May 2012 over Brignoles, located in southeastern France. The event was observed by an X-band polarimetric radar located in Mont Maurel, 75 km northeast of the ...
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 ...
