Microphysical retrievals of dual polarization and dual frequency ground radar for GPM ground validation

A dual-frequency precipitation radar (DPR) will be deployed aboard GPM (Global Precipitation Measurement) core satellite in order to enhance our knowledge of precipitation microphysics. A ground based dual-frequency (Ku and Ka band) and dual-polarization radar D3R is being built to perform cross validation with GPM-DPR which helps provide insight into the physical basis of the retrieval algorithm. This paper is the follow up study of the author´s previous paper where a new drop size distribution (DSD) retrieval algorithm was proposed. In this paper, the algorithm evaluation is extended to the complete region including rain, melting ice and ice based on simulation data. A possible method to classify the hydrometeor identification for dual-frequency and dual-polarization ground radar is also proposed which might be applied to D3R.
