NJU-CPOL dataset including variables of reflectivity (dBZ), differential reflectivity (ZDR) and specific differential phase (KDP), at height of 3 … 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 … Zobraziť viac The radar reflectivity factor (Z) of precipitation is dependent on the number (N0) and size (D) of reflectors (hydrometeors), which includes rain, snow, graupel, and hail. Very sensitive radars can also measure the … Zobraziť viac The definition of Z above shows that a large number of small hydrometeors will reflect as one large hydrometeor. The signal returned to the radar will be equivalent in both situations, so a group of small hydrometeors is virtually indistinguishable … Zobraziť viac

Web23. dec 2015 · Negative dBZ values are the result of equivalent reflectivity between 0 and 1. These dBZ values are what is typically used to express reflectivity, thus they are often referred to simply as intensity. Most color tables (figure 1) used in radar images have dBZ values ranging from -10 or 0 to 80 dBZ. Figure 1: Some of the commonly used color ...
