A reformatting system that will convert the Global Precipitation Measurement (GPM) products into Binary Universal Form for the Representation of meteorological data (BUFR) and GRIdded Binary Edition 2 (GRIB2) formatted files is under development at NASA/GSFC Precipitation Processing System (PPS). This Reformatting System will convert the products of the Tropical Rainfall Measuring Mission (TRMM), GPM, and their constellation satellites into BUFR and GRIB2 files. The current toolkit development schedule consists of four phases, each adding new tailoring capabilities. In phase 1, the common calibrated brightness temperature products (1C) for the GPM core and constellation satellites will be converted into BUFR files. In phase 2, this software system will reformat the Integrated Multi-satellitE Retrievals for GPM (IMERG) 30-minute and monthly data into GRIB2 files. In phase 3, the GPM GMI Goddard Profiling Algorithm (GPROF) products and its constellation satellites GPROF products will be converted into BUFR files. In phase 4, this software will reformat daily and monthly GPM GMI and its constellation satellites GPROF products, and the Dual-frequency precipitation radar (DPR) products into GRIB2 files. Currently, the system has implemented the phase 1, phase 2 and phase3 tasks. The implemented part of converter is running at the PPS. Its BUFR/GRIB2 files can be accessed through the PPS Science Team On-line Request Module (STORM). PPS is reprocessing the TRMM era data with the retrieval algorithms based on the GPM V05 algorithms. With this approach, PPS will create the consistent retrieval products from December 1997 (the beginning of TRMM) through the current ongoing GPM. This 20+ years global precipitation data will benefit the user community. The details of this system design and its products will be discussed.
