Dual-wavelength radar was used routinely to observe and record, in digital form, severe convective storms in northeastern Colorado in 1972-1974. By postprocessing, the precipitation-caused attenuation of the attenuating wavelength of the dual-wavelength pair is determined while the other wavelength remains essentially unattenuated. Precipitation rate computed from this attenuation is more accurate...
Polarization and dual-wavelength radar data are presented for two days on which a radar bright band was observed. The polarization parameters (reflectivity, Circular Depolarization Ratio, and the phase correlation between the main and orthogonal components) are found to yield interpretations about the hydrometeors that are consistent with those obtained from the ratio of the 10- and 5-cm reflectivity...
In this paper, the authors describe a system of two Doppler radars (the RONSARD system) operated for the study of precipitating clouds (fronts and convective storms). In a first part, emphasis is placed on the system requirements concerning both transportability and flexibility, due to the wide range of atmosphere phenomena to be observed. These requirements lead to an original implementation of the...
