The issues with NOAA's 4-km Merged IR data are closed and the IMERG Early and Late Runs have been restarted from the point at which they stopped. This will provide a continuous record for each, but it also means that it will take a while to process the backlog of data and catch up to the nominal latency.
TRMM/PR data distribution resumes during the experimental operation period. The satellite has descended to an altitude of around 350 km on February 12, 2015, which is the original nominal altitude before 2001. Verification of the data quality concluded and JAXA and PPS started distribution of PR data around the 350 km altitude (orbit number from 98231) to the public. PR available data period around 350 km altitude will be about 40 days since February 12, 2015.
The most accurate and comprehensive collection of rain, snowfall and other types of precipitation data ever assembled now is available to the public. This new resource for climate studies, weather forecasting, and other applications is based on observations by the Global Precipitation Measurement (GPM) Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA), with contributions from a constellation of international partner satellites.
This section outlines the primary sources for downloading GPM and TRMM precipitation data from archive sites at Goddard Space Flight Center, including basic instructions for using each source.

The GPM Core Observatory satellite was successfully launched on February 27th, 2014. Data from the GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) have the following release schedule. All data are freely available through the NASA's Precipitation Processing System at http://pps.gsfc.nasa.gov
June 16th – GMI Level 1 Brightness Temperature data have been released. This includes GMI instrument swath data.
