Modeling and Assimilation Innovation

Summary and Expectations

This session will focus on ocean reanalyses, beginning with an update from recent assessment and inter-comparison studies, including recent advances and unsolved challenges, developing a vision for sustainable and integrated global ocean observations for climate monitoring and reconstructions, including observational needs for climate products. The discussion will focus on the use of observing system impact studies to improve the optimal deployment of observations and maximize their uptake in climate products and the use of coupled DA to maximize extraction of ocean observational information for improving ocean reanalyses, climate products, and prediction.

Expected Outcomes/Recommendations

• Promote investment for organizing workshops, training programs, and targeted meetings in order to enhance the communication between observational and modeling/Data Assimilation (DA) communities.
• Encourage Observation System Experiments (OSEs) and Observation System Simulation Experiments (OSSEs) to identify best practices.
• Utilize model/DA for designing/redesigning observation network, and for planning observation field campaigns to improve modeled physical processes.
