Abstract: The choice of the boundary condition when integrating the air mass continuity equation, is a major problem of the 3D wind field analysis from dual (or multiple) Doppler radar data. A zero vertical velocity at ground level ...

Abstract: This paper is the first of three dealing with the three-dimensional wind field analysis from dual-Doppler radar data. Here we deal with the first step of the analysis which consists in interpolating and filtering the raw ...

Abstract: This paper presents a new concept in the measurement of precipitation by radar. The principle consists of stereoscopic observations: the same precipitation cell is observed by two radars operating at the same attenuated ...

Abstract: During May and June 1981 several French research organizations, the University of Abidjan (Ivory coast) and the Agency for security of Aeronautical Navigation (ASECNA), participated in the observational field program called ...

Abstract: Recently, 95-GHz Doppler radars have been developed to document microphysical and dynamical properties of nonprecipitating clouds. RALI (airborne radar and lidar) plans to associate a dual-beam 95-GHz Doppler radar and a ...

Abstract: One of the major problems in three-dimensional wind field analysis from dual (or multiple) Doppler radar data resides in the non-stationary of the observed air flow within the volume sampling time which ranges typically ...

Abstract: Airborne Doppler radar is an important meteorological research tool for sampling the flow field of large convective systems (hurricanes, squall lines, fronts, etc.). In order to improve space resolution, the next generation ...

Abstract: Several space agencies are presently considering missions with active instruments (radar, lidar), which are able to document cloud stratification and cloud microphysical properties on the global scale. The objective of ...

Abstract: This paper is based on the observation of a cold front using a C-band Doppler radar. The extent of the precipitation system associated with the front allowed collection of Doppler radar data during 12 consecutive hours. ...
