=== Rainfall observation ===
Since Japan is an island nation and gets struck by typhoons every year, research about the dynamics of the atmosphere is a very important issue. For this reason Japan launched in 1997 the [[TRMM]] (Tropical Rainfall Measuring Mission) satellite in cooperation with NASA, to observe the tropical rainfall seasons. For further research NASDA had launched the ADEOS and ADEOS II missions in 1996 and 2003. However, due to various reasons,{{specify|reason=what would those reasons be?|date=November 2017}} both satellites had a much shorter than expected life term.

On 28 February 2014, a H-2A rocket launched the [[GPM Core Observatory]], a satellite jointly developed by JAXA and NASA. The GPM mission is the successor to the TRMM mission, which by the time of the GPM launch had been noted as highly successful. JAXA provided the [[Global Precipitation Measurement]]/Dual-frequency Precipitation Radar (GPM/DPR) Instrument for this mission. Global Precipitation Measurement itself is a satellite constellation, whilst the GPM Core Observatory provides a new calibration standard for other satellites in the constellation. Other countries/agencies like France, India, ESA, etc. provides the sub-satellites. The aim of GPM is to measure global rainfall with unprecedented detail.
