Ice depolarization characteristics on Ka-band satellite-to-ground path obtained from the CS-3 beacon signal observations

The mean ice depolarization obtained from the CS-3 beacon signal observations (19.45 GHz, RHCP) from 1988 to 1992 is examined. The ice depolarization component above the rain height is derived by subtracting theoretical rain depolarization calculated from the rain attenuation. In these events, the ice depolarizations indicate much the same characteristics of amplitude and phase as those directly detected in the pure ice depolarization events without appreciable rain depolarizations. This strongly supports the validity of the present estimation of the ice depolarizations and their common process despite the difference of rainfall types.<>
