Adjoint Sensitivity

Objective: To diagnose the dynamics and sensitivities of the ocean circulation fields using data assimilation experiments with observed mesoscale oceanic surveys of the VOCALS observations and a regional ocean modeling system.

Tracer Experiments

Location of tracers in the initial forcing for the adjoint model run.

90 day prior Adjoint Sensitivity

Location of the tracers indicating regions of sensitivity to the region above 90 days prior to the day the tracers were injected into the domain.

Summary: Surface adjoint sensitivity of the South East Pacific ocean domain in an adjoint sensitivity test case was run for 90 days to test the sensitivity of the coastal region to surrounding coastal flows. Sensitivity to strong coastal upwelling and the Humboldt current was evident from the simulations.
