Migrasi TRMM Ke GPM IMERG

Misi TRMM telah berakhir, data yang tersedia hanya sampai tanggal 31 Desember 2019 saja. Hal tersebut diumumkan melalui web site https://pmm.nasa.gov/data-access/downloads/trmm.

UPDATE: The TRMMOpen FTP server has been shut down as of December 31st, 2019, coinciding with the scheduled end to TMPA production. Historical TMPA data will be made available on the GPM FTP servers in the near future. Our team is in the process of updating the links on this webpage to reflect this change, but in the meantime some of the URL's listed may be non-functional. Historical TMPA data can also be download from the NASA GES DISC at: https://disc.gsfc.nasa.gov/datasets?keywords=TMPA&page=1

TRMM Mission Comes to an End

After over 17 years of productive data gathering, the instruments on TRMM were turned off on April 8, 2015. The spacecraft re-entered the Earth’s atmosphere on June 15, 2015, at 11:55 p.m. EDT, over the South Indian Ocean, according to the U.S. Strategic Command’s Joint Functional Component Command for Space through the Joint Space Operations Center (JSpOC), and most of the spacecraft was expected to burn up in the atmosphere during its uncontrolled re-entry. The Tropical Rainfall Measuring Mission (TRMM), a joint mission of NASA and the Japan Aerospace Exploration Agency, was launched in 1997 to study rainfall for weather and climate research.
The GPM IMERG dataset now includes TRMM-era data going back to June 2000, and is now the recommended multi-satellite dataset to use for most purposes. The multi-satellite 3B42* / TMPA / TMPA-RT dataset ended on December 31, 2019.  Learn more about  the transition from 3B42*/TMPA to IMERG.
