ZDR Against Range Plot (ZDR)

If you have the ZDR option, this plot is generated when you choose the ZDR plot parameter.

The differential reflectivity is the ratio of the reflectivity at vertical polarization to the reflectivity at horizontal polarization. The range displayed is roughly -8 ...  +8 db.

Similar to the spectrum width, the numerical value of the ZDR in dB is displayed for the selected range (as indicated by vertical yellow line).
