JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21ER2402 Subject Category: Space Technology PDF Responsible Representative: Misako Kachi, Earth Observation Research Center Contact Information: Misako Kachi(kachi.misako@jaxa.jp) Members: Misako Kachi, Shun Ohishi Abstract With the recent enhancement of observation networks such as satellites and Argo floats, temperature, salinity, and sea surface height have been observed at relatively high spatiotemporal resolution. However, for example, the satellites cannot observe rainy regions and the number of Argo float observations is still not・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA53 Subject Category: JSS Inter-University Research PDF Responsible Representative: Naofumi Ohnishi, Professor, Tohoku University Contact Information: Yasuhito Okano, Tohoku University(yasuhito.okano.p4@dc.tohoku.ac.jp) Members: Naofumi Ohnishi, Hiroki Sakamoto, Yasuhito Okano Abstract In hypersonic flight, turbulent transitions cause an increase in aerodynamic heating. Therefore, predicting transition locations is an extremely important research issue. Since experiments are not easy to reproduce hypersonic flow and require huge cost to operate, numerical simulations are preferable. In this・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EU0904 Subject Category: Space and Astronautical Science PDF Responsible Representative: Ikkoh Funaki, Professor, ISAS Contact Information: Ikkoh Funaki(funaki.ikkoh@jaxa.jp) Members: Ryuta Futada, Yuki Murayama Abstract Due to the limitation of the existing spacecraft technology level, it is very difficult to enable solar system explorations in a quick and cost-effective mannger. Objective of this study is to obtain a breakthrough spacecraft propulsion technology that enables solar system exploration of the next generations.・・・<<read more>>
