"dBZ stands for decibel relative to Z. It is a logarithmic dimensionless technical unit used in radar, mostly in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm per m ) to the return of a droplet of rain with a diameter of 1 mm (1 mm per m ). It is proportional to the number of drops per unit volume and the sixth power of drops' diameter and is thus used to estimat… " - Reflectivity unit
