JSPS Sakura project
JSPS Sakura project: Joint research between France and Japan
|
*
|
Two-year project (2016-2018) funded by JSPS (Japan) and MAEDI (France) joint Sakura exchange programme. |
|
*
|
Proceeding of our understanding on physical processes of Jupiter’s and Saturn’s aurora as well as tansient and periodic processes in their magnetosperes which control mophorogy and time variavility of the auroral phenomena. |
|
*
|
Sharing observed data from spacecraft and ground-based facilities, analysis tools, and nummerial models between Japanese and French comunities. |
