Termination of Updates for GSMaP Algorithm Version 7

The updates for the standard products of the Global Satellite Mapping of Precipitation (GSMaP) algorithm version 7 (v7), which have been provided via the FTP site, were terminated on May 31, 2026. This applies to the following products:
   GSMaP_MVK
   GSMaP_Gauge
In addition, updates for the v7 near-real-time products will also be terminated shortly. This applies to the following products:
   GSMaP_NRT
   GSMaP_Gauge_NRT
Please note that the previous v7 data, as well as algorithm versions 6 (v6) and 8 (v8), will continue to be available.

Details of the affected products, FTP site directories, and their respective availability periods are as follows:

Standard products (GSMaP_MVK, GSMaP_Gauge)

12 years have passed since the GPM Core Observatory was launched!
12 years have passed since the GPM Core Observatory was launched from the JAXA Tanegashima Space Center on February 28, 2014! The GPM Core Observatory continues to observe the global precipitation till now. Taking over the will of TRMM, we hope that the GPM Core Observatory will live longer.

[Quick Report] Hurricane Humberto "Eye" captured by EarthCARE satellite (Hakuryu)
Hurricane Humberto, which developed off the U.S. East Coast, reached its peak strength on September 27, 2025, intensifying into a powerful Category 5 storm - the highest level on the scale.
The Earth Cloud Aerosol and Radiation Explorer (EarthCARE) satellite, jointly developed with the European Space Agency (ESA) and also known by its Japanese nickname Hakuryu ("White Dragon"), observed Hurricane Humberto as it moved northeast off the U.S. East Coast on 28 September 2025.

"JAXA/EORC Typhoon Database" Update – Added Observational Images of Typhoon Cloud "Cross-Sections" by the EarthCARE satellite "Hakuryu"
JAXA has launched the "JAXA/EORC Typhoon Database" website, which provides data on typhoons worldwide (including tropical cyclones such as typhoons and hurricanes) observed by the Tropical Rainfall Measuring Mission (TRMM), the Global Precipitation Measurement (GPM) Core Observatory, About Global Change Observation Mission – Water "SHIZUKU" (GCOM-W)), and others.
Starting from 1st October 2025, new observational images captured by the Earth Cloud Aerosol and Radiation Explorer (EarthCARE) (Japanese nickname: Hakuryu), which was jointly developed with the European Space Agency (ESA), such as vertical cross-sections of clouds around typhoons and cloud images from the Himawari geostationary meteorological satellite, have been added to this website.
