Plain Language Summary: The Global Precipitation Measurement (GPM) Dual-Frequency (DF) Precipitation Radar (DPR) has operated in full scan (FS) mode in both the Ku-band and Ka-band since May 2018. For the first time in the DPR level 2 (L2) version V06X experimental algorithms, the DF processing has been made on the 245 km wide full swath data. In previous versions up to V06A, the DF processing is limited to the 125 km wide inner swath data only. This paper describes the V06X precipitation type classification algorithm that detects bright-band (BB) and classifies precipitation as stratiform, convective, and other.

Highlights:

• The GPM DPR L2 V06X algorithms output the DF processed FS data for the first time.
• The DF processing in the precipitation type classification algorithm works well not only in the inner swath but also in the outer swath.
• The advantage of the DF processing shows up in the detection of BB in the outer swath.
