ESGF/CSSEF uses Globus Online for data transfer solutions. Globus Online addresses the challenges faced by researchers in moving, sharing, and archiving large volumes of data among distributed sites. With Globus Online, you hand off data movement tasks to a hosted service that manages the entire operation, monitoring performance and errors, retrying failed transfers, correcting problems automatically whenever possible, and reporting status to keep you informed so that you can focus on your research. Command line and web-based interfaces are available. The transfer process can be started and monitored from any location with an Internet connection, e.g. from your university, airport, or home.
