ROMS Tangent Linear and Adjoint Models: Testing and Applications

Abstract

Our long-term technical goal is to produce a tested tangent linear and adjoint model for ROMS (Regional Ocean Modeling System) that is suitable for general use by ROMS modelers. This is complementary to the Kalman Filter, ESSE, and Green's Functions techniques being developed in other contexts. Our long-term scientific goal is to model and predict the mesoscale circulation and the ecosystem response to physical forcing in the various regions of the world ocean through ROMS primitive equation modeling/assimilation. We seek to develop an adjoint model for the Rutgers/UCLA Regional Ocean Modeling System (ROMS) which is a parallel/improved physics descendent of the serial SCRUM (Song and Haidvogel, 1994). We also seek to complete the assimilation system by including the adjoint in an estimation procedure for fitting the model to data. The resulting codes will be suitable for general use in any geometry of ROMS, which presently lacks an adjoint.
