Using PALM to integrate variational data assimilation algorithms with OPA/NEMO

Objective

General formulation of the CERFACS variational assimilation system (OPAVAR)

Minimization

The transformation (G) from the control space (v) to observation space (y) can be summarized as:

The linearized transformation (G) can be summarized as:
