I. Introduction
ROMS [1] is an ocean model widely used by the scientific community for a wide range of climate applications. It can work standalone as well as it can be coupled to atmospheric and/or wave models. It is built based on the Earth System Modeling Framework (ESMF) [2] which provides high per-formance and flexibility for coupling climate and related other scientific applications. The format of the input and output data of the model are Network Common Data Form (NetCDF) [3] which helps to interchange the data in a user-friendly way.
