Data Access Method
List of GOSAT-2 Products

There are two methods for data access: "Direct sftp acquisition" and "Search and Order"

No.	Method	Description	Target User Category	Restriction
1	Direct sftp acquisition	With the sftp client, archived products can be acquired directly (No order required). Suitable for acquiring massive data all at once or acquiring data regularly.	General User Authorized User	[Data Capacity] There is no capacity limit. [The number of connected session] 10 sessions [Target Data] Standard Products : "General User"; "Authorized User" Research Product : "Authorized User" Internal Products : "Approved Authorized User"
2	Search and Order	From the web page, enter search criteria (observation period, area, etc.), search for products, and order products that match the criteria. Suitable for acquiring products with specified observation period, area, etc.	General User Authorized User	[Data Capacity] The size of data which can be ordered at a time differs depending on the user category. When the ordering data size is larger than the limit, order data separately in multiple times. There is no daily capacity limit.
