Abstract
Process ALOS/PALSAR data to Analysis Ready Data (ARD) and distribute to users.

Please refer to 'JAXA | Advanced Land Observing Satellite-2 "DAICHI-2" (ALOS-2)'.
Reasons for using JSS2
In order for enhancing availability of JAXA's Earth observation data as Open and Free, it is necessary to process the ALOS/PALSAR data to Analysis Ready Data (ARD) and make them available to users as quick as possible.
Achievements of the Year
In this Fiscal Year 2017, a feasibility study on transmitting some sample ALOS/PALSAR Level 0 data from Tsukuba Space Center to JSS2 and also processing the data to Level 1.0 and 1.5 in SORA-PP has successfully conducted.
In next Fiscal Year 2018, whole ALOS/PALSAR Level 0 data (700TB) will be transmitted and processed to Analysis Ready Data (ARD). The ARD will be archived in JSPACE and will be able to retrived and distributed to users.
