The ultimate objective of this paper is the estimation of rainfall over an area in Algeria using data from the SEVIRI radiometer (Spinning Enhanced Visible and Infrared Imager). To achieve this aim, we use a new Convective/Stratiform Rain Area Deline

The shape of the drop size distribution (DSD) reflects the physics of rain. The DSD is the result of the microphysical processes that transform the condensed water into rain. The question of the DSD is also central in radar meteorology, because it ru

The algorithm developed in this paper for ground-based polarimetric radars is derived from those used for the spaceborne rain radar of TRMM (Tropical Rainfall Measurement Mission)—the so-called rain profiling algorithms. The characteristic of this

This paper compares the performances of several algorithms for profiling the rain rate from a spaceborne radar. Three techniques are considered: single frequency (or SF) at 13.8, or 24 GHz; dual frequency (or DF) at 13.8 and 24 GHz; and dual beam (or

The detailed structure of a tropical squall line observed in central Florida was investigated from an airborne dual-beam Doppler radar, pointing respectively fore and aft. This allowed dual-Doppler observations from a straight flight path in a way si

The development of airborne Doppler radars for atmospheric sciences research has vastly improved the ability to measure atmospheric storms. This paper addresses a new technique for improving airborne Doppler radar data quality. Assuming the earth's s

The potential characteristics and performances of a spaceborne dual-beam radar (or stereo radar) operating at 24 GHz, and devoted primarily to the retrieval of rain-rate structure by using the stereo-radar analysis, were presented in a previous study
