What Does ZDR Stand For?

ZDR stands for Differential Reflectivity

ZDR, or Differential Reflectivity, is a radar measurement that quantifies the difference in reflectivity between horizontal and vertical polarized microwave signals. It is primarily used in meteorology to distinguish between precipitation types, such as rain, snow, and hail, and to assess their size and distribution. By analyzing ZDR values, meteorologists can enhance weather forecasting accuracy and improve the understanding of storm structures and dynamics.
