Abstract

This paper discusses an application of polarimetric measurements at vertical incidence. In particular, the correlation coefficients between linear copular components are examined, and measurements obtained with the NSSL's and NCAR's polarimetric radars are presented. The data are from two well-defined bright bands. A sharp decrease of the correlation coefficient, confined to a height interval of a few hundred meters, marks the bottom of the bright band.
