Dual-polarization Developments at CNR: Past and Present Research

This paper reviews the research activities carried out by the radar meteorology group that was established at the Institute of Atmospheric Physics of the National Research Council of Italy. The group started in the late 1970s, and, after the publication of a keystone paper on the use of linear polarization by Seliga and Bringi (1976), its primary focus has been on po- larimetric radar techniques and their meteorological applications. The research efforts, realized through close cooperation first with Pennsylvania State University and later with Colorado State University, have produced positive results that have contributed to a spread in the knowledge of dual- polarization techniques and in learning important information about microphysical processes in clouds and precipitation. This paper highlights some of these research achievements.
