Polarimetric estimation of rainfall provided more reliable and accurate data than that of conventional radars. This paper aims to provide the application of Polarimetric radar in the estimation of heavy rainfall by its conventional use, provides analysing technique, relate the algorithms to measure rainfall rates, compares its efficiency to conventional radars, gauges and analyses few examples observed before to provide a schematic view about its uniqueness in its behaviour. These examples provide a better view in the estimation of the rainfall by Polarimetric rainfall. The paper produces details about the rain drop size and shape, rain drop distribution, areal mean rate values, average drop sizes and various concordances are discussed here. Moreover the properties and parametric values of rain fall and its estimates, β and axis ratio relation are also described in this paper
