Abstract: An analysis to determine the frequency of occurrence of gradients in reflectivity has been performed. Gradients as large as 50 dB km?1 occur with a frequency of over 1% of the pairs of adjacent nonzero reflectivities at ...

Abstract: As radar waves at different polarizations propagate through a medium of nonspherical, oriented scatterers a phase difference between the waves appears. A method is proposed for estimating this propagation-differential phase ...

Abstract: The measurement of the differential propagation phase and copolar correlation coefficient are affected by the differential phase pattern of the antenna system when operating in an alternate horizontal and vertical transmitting ...

Abstract: Recent research has suggested that the copolar correlation coefficient termed ?h?(0) can be used to identity large hail and improve polarization estimates of rainfall. The typical measured values of ?h?(0) at S band vary ...

Abstract: The subject of this paper is the Colorado State University?University of Chicago?Illinois State Water Survey (CSU?CHILL) National Radar Facility?s S-band polarimetric research radar. Key features of this system include ...

Abstract: The advantages of three or more radars is illustrated in terms of extended areal coverage, error variance reduction and mitigation of poor sampling effects of divergence fields near the ground. Errors in the horizontal and ...
