Introduction

The Modular Ocean Model (MOM) is a numerical representation of the ocean's hydrostatic primitive equations. It is designed primarily as a tool for studying the global ocean climate system, as well as capabilities for regional and coastal applications.

In order to use the software package the corresponding module needs to be loaded: module load mom
This adds the various executables like MOM_run.csh, mppnccombine, fms_ESM2M.x, fms_EBM.x, etc. to the PATH. The MOM_run.csh script is setup such that it uses the MOMROOT environment varible to find the various files necessary for the computation. By default MOMROOT is set to the system directory /usr/local/mom and the working directory is set to the directory work within the current directory (i.e., the directory from which MOM_run.csh is run). In this case the various input files for the test cases like atlantic1, baltic1, box1, dome1, etc. that come with the MOM code are found in /usr/local/mom/data/<name>/INPUT, where <name> is a placeholder for the case (e.g., atlantic1). If the MOMROOT environment variable is changed from its default setting, the necessary input files need to be copied to the $MOMROOT/work/<name>/INPUT directory and the working directory is set to $MOMROOT/work. In either case the  MOM_run.csh will create the work/<name> directory where all other files (e.g., RESTART files, log files, etc.) will be saved. MOM_run.csh will use the files input.nml, data_table, diag_table, field_table from this directory and will copy these files from the INPUT directory to the $MOMROOT/work/<name> directory unless the files exist already. Therefore, if a calculation is to be run with modified input.nml and/or data_table and/or diag_table and/or field_table files, the modified files need to be copied to the $MOMROOT/work/<name> directory before MOM_run.csh is run.
