Weather Radar Polarimetry: What is next?

After decades of research and development, weather radar polarimetry has been implemented on the national NEXRAD (WSR-88D) network, providing multi-parameter polarimetric radar data (PRD). Furthermore, weather radar networks in other countries also have radars capable of producing multi-parameter PRD.  While the technology of radar polarimetry has matured, and PRD are available nationally and globally, the operational usage of radar polarimetry is still in its initial stages, and polarimetric phased array weather radar technology is still in its exploration stage. There is much room for research and development. In this talk, the motivation behind and a summary of the newly published textbook Weather Radar Polarimetry will be given. The issues and approaches of how to optimally utilize PRD for quantitative precipitation estimation (QPE) and forecast (QPF) will be discussed. The status and challenges of polarimetric phased array radar research and development will be reviewed, and possible solutions will be examined.

Dr. Zhang received his B.S. degree in Physics from Anhui University and M.S. degree in Radio Physics from Wuhan University, China. His Ph.D. is in Electrical Engineering from the University of Washington. Prior to joining SoM, he worked as a scientist in the National Center for Atmospheric Research. His  research interests include the modeling of wave propagation and scattering in geophysical media and the development of remote sensing techniques for environmental monitoring.
