June 16th – GMI Level 1 Brightness Temperature data have been released. This includes GMI instrument swath data.

July 14th – GMI Level 2 Precipitation Rate data will be released. This includes precipitation rates estimated using the Goddard Profiling algorithm (GPROF14) and are available as swath data.

Early September – DPR Level 2 precipitation rate data will be released via PPS and JAXA. This includes three-dimensional swath data from the DPR Ka and Ku-band radars.

Mid-September - The DPR-GMI Level 2 combined product will be released

December 2014 – NASA’s Level 3 Integrated Multi-Satellite Retrievals for GPM (IMERG) will be released with all available data. This gridded product will have a resolution of 0.1 degrees and updated every 30 minutes from 60⁰N-60⁰S.
