This dataset includes Unprocessed Signal Data Product Data. Data which has undergone absolutely no correction is recorded. Data required for higher level correction is ALOS recorded. It is same as the unprocessed data of other sensors prepared at the EOC. The provided format is CEOS. series JERS-1_SAR_L0_Data eng -90.0 -180.0 90.0 -180.0 90.0 180.0 -90.0 180.0 -90.0 -180.0 No constraints but users need to be registered with [the G-portal User Registration system](https://gportal.jaxa.jp/gpr/user/regist1?lang=en) to download files.
