Developmenet of an EnKF-based ocean data assimilation system

[Added on] [Last modified on]

JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20ER2402 Subject Category: Space Technology PDF Responsible Representative: Riko Oki, Space Technology Directorate I, Earth Observation Research Center Contact Information: Misako Kachi(kachi.misako@jaxa.jp) Members: Misako Kachi, Shun Ohishi Abstract With the recent development of satellites, sea surface temperatures at high spatiotemporal resolutions have been observed by infrared sensors, but the data is not available in the cloudy regions because clouds block infrared radiations. Data assimilation can estimate more accurate 3-dimensional ocean・・・<<read more>>
