Specific Differential Phase is a measurement of difference between the horizontal and vertical pulse phase changes as they travel through the atmosphere. Interpreting Specific Differential Phase (KDP) can be very difficult. Its primary use involves detecting areas of heavy rain. KDP values are largest when going through areas dominated by large raindrops. In some cases, regions with high KDP values may also contain melting hail. The four lowest elevation angles are available.
