What happened to the TRMM Multi-satellite Precipitation Analysis (TMPA / 3B4x) data products?

The TRMM satellilte has been decommissioned and stopped collecting data in April 2015. The transition from the Tropical Rainfall Measuring Mission (TRMM) data products to the Global Precipitation Measurement (GPM) mission products has completed as of August 2019. The GPM IMERG dataset now includes TRMM-era data from June 2000 to the present, and other TRMM-era data has been reprocessed with GPM-era algorithms and is now available on the GPM FTP servers. TMPA data production ended as of December 31st, 2019 and the TRMMOpen FTP server has been shut down.

Rain Brought Brief Relief to Australia
For much of the 2019-2020 austral summer, plumes of bushfire smoke have billowed from southeastern Australia in such large amounts that the ground was barely visible in satellite images. In mid-January, some of those plumes were finally quelled by a few days of much-needed rainfall.

GPM & TRMM Data Usage Policy GPM and TRMM data are freely available at all levels for which the particular sensor or sensor combination has been processed by GPM. For the GPM Core Observatory this is for Levels 0 through 3 products (as applicable). For the partner satellites in the GPM constellation this is Levels 1c through 3 (as applicable). Users are encouraged to access data from the primary GPM and TRMM archives (i.e. nasa.gov domains at Goddard Space Flight Center). When data from secondary archives are used, it is incumbent on the user to verify that the data values accessed are
