Depolarization ratio (LDR) is the ratio of the perpendicular or cross-polarized (XPOL) components and parallel (PPOL) signal components.
The following figure presents the same time period as Figure 1, Figure 2 and Figure 3.
The linear depolarization ratio reveals the precipitation between 3 000 m and 4 000 m (9843 ft and 13 123 ft) to consist of non‑symmetrical solid particles. The ratio falls near zero at the beginning of the cloud signal, signifying a liquid cloud. The ratio increases inside the liquid cloud due to the presence of multiple scatterers.
