These sessions are devoted to current and next generation weather radars, with emphasis on radar meteorology science, weather radar applications, weather radar signal processing, weather radar prototype developments, experimental weather radar data collections, and essentially all radar meteorological algorithms. Presentations about advanced radar technologies, including phased array radars, polarimetry, multi-function scan strategies, retrieval algorithms, signal processing for clutter rejection, etc. will be a focus of these sessions. Outcomes could include radar measurements in the context of numerical model assimilation and radar-based short term forecasts. Example of presentations may include the SENSR initiative, the dual-pol WSR-88D, etc.
