Reasons and benefits of using JAXA Supercomputer System
JAXA is developing data disclosure to expand the use and spread of earth observation satellite data.
As part of this, the previous system JSS2 processes the data for the entire ALOS / PALSAR observation period and archives a large amount of data in J-SPACE.
We used the JSS system to quickly provide this data to external users. (Provided via medium (NAS) or transmission server.)
Achievements of the Year
- PALSAR / FBD 620TB
AVNIR-2 4TB
Provided using NAS. Conducted 19 times in total.
This year, we received 19 transportation support and carried out 17 copying work. (Two copies were completed last year)
- PALSAR / FBS L1.1 1402TB
L2.1 65TB (North America 2007 / 7-2011 / 4)
Data is provided in a total of 39 sets, including 23 sets of NAS and 16 sets via a transmission relay server.
Work started in the latter half of 2021.05, and provision was completed in the middle of 2022.01.
- Provide the following data to NASA / ASF by sftp-get by sshgate connection
PALSAR / FBD
PALSAR / FBS (L2.2)
- Providing AVNIR-2 data 339 scenes for GSI via transmission relay server
- 21 scenes of PALSAR FBS / FBD to JGI (Earth Science Institute)
Provided via EORC_FTP
- PALSAR L2.2 PLR @ Japan 152 scenes for NICT are provided via NICT file transmission / reception system.
