Data assimilation in Mercator systems

Mercator Ocean implements several great families of numerical methods allowing data assimilation in ocean models:

• Optimal interpolation
• Kalman - SEEK
• Variationnel

Current operationnel systems versions (PSY1V2, PSY2V2, PSY3V1, PSY2G) are operating optimal interpolation schemes. PSY3V2 global system will implement in 2007 the SEEK method.
