V04 Processing processing of GMI GPROF retrievals began at 11:20 UTC, May 2.
Please note the the GPM Near-realtime (NRT) subsystem began to run the V04A GPROF precipitation retrieval effective 11:20UTC, May 2, 2016.
The biggest change in the retrieval is the use of an a-priori database constructed from Combined and KU actual mission retrievals rather than the pre-launch composite databases.
Partner radiometer (both conincally scanning and cross-track) still use the V03 retrieval at this time.
These changes may also be reflected in the IMERG NRT products.
