Abstract.
The Inverse Ocean Modeling System (IOM) is modular system for constructing
and runningWeak constraint 4-DimensionalVARiational assimilation
(W4DVAR) for any linear or nonlinear functionally smooth dynamical
model and observing array. The IOM has been applied to four ocean models
with widely varying characteristics. The Primitive Equations Z-coordinate -
Harmonic Analysis of Tides (PEZ-HAT) and the Regional Ocean Modeling
System (ROMS) are three-dimensional, primitive equations models while
the ADvanced CIRCulation model in 2D (ADCIRC-2D) and Spectral Element
Ocean Model in 2D (SEOM-2D) are shallow water models belonging
to the general finite element family. These models, in conjunction with the
IOM, have been used to investigate a wide variety of scientific phenomena
including tidal, mesoscale and wind-driven circulation. In all cases, the assimilation
of data using the IOM provides a better estimate of the ocean
state than the model alone.
