Purpose of the meeting
To provide an update on the recent progress on regionalization and path/source issues for NGA-East (tasks C and D from the project plan). Results will be presented by members of the Path/Source Working Group and by other contributors performing work on some of NGA-East’s critical issues topics. The meeting schedule was designed to allow plenty of time for and to stimulate scientific discussions amongst the participants. The format and interactions are more flexible than for official SSHAC Workshops.
