Preliminary Analysis of Experimental Product for the New Scan Pattern of GPM/DPR

Dual-frequency Precipitation Radar (DPR) on the core satellite of Global Precipitation Measurement (GPM) mission has changed its scan pattern in May 2018. As the high-sensitivity measurement of KaPR has been moved to the outer swath from the inner swath, all pixels are measured by both KuPR and KaPR after the scan pattern change. Experimental product (DPR Version 06X; V6X in short) for the new scan pattern applies dual-frequency algorithm for the outer swath. In this study, precipitation rates and other outputs of V6X are analyzed. Dual-frequency algorithm of V6X shows strong incident angle dependence of precipitation rates in the outer swath.
