Towards A Mathematical Advancement of Data Assimilation

This workshop aims to explore future mathematical and statistical directions and perspectives to advance data assimilation further beyond the current state-of-the-art. Primary goals of this workshop are to: 1) integrate relevant scientific areas; and 2) exploit the role of fundamental research it in data assimilation which is motivated by operational applications.This workshop also serves as the grand finale of the SAMSI DA Program, Spring 2005.

There will be additional discussion opportunities and a poster session at the subsequent workshop on "Collaborations in Mathematical Geosciences (CMG)", October 6 and 7, 2005, at the nearby Radisson Hotel Research Triangle Park. Participants of this workshop are most welcome to attend the CMG workshop also.
