Project Abstract:

This project will complete work that was begun as part of a project entitled “Toward the Development of a Coupled COAMPS-ROMS Ensemble Kalman Filter and Adjoint with a focus on the Indian Ocean and the Intra-seasonal Oscillation” that was supported by the NOPP. Specifically, complete the development and testing of a coupled model capability based on the Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS) and the Regional Ocean Modeling System (ROMS) using the Earth System Modeling Framework (ESMF). Tests will be performed first in the coupled model configured for the U.S. west coast, after which the system will be transitioned to the Indian Ocean. As addition component of the project is to complete the development of the interface between COAMPS and the Data Assimilation Research Testbed (DART) which allows for data assimilation in COAMPS using an Ensemble Kalman Filter (EnKF) approach. DART has been successfully configured with ROMS, and a detailed comparison with the ROMS 4-dimensional variational (4D-Var) data assimilation system is underway.
