    14 Creation of an offline tool (SCOORD_GEN) to generate a vertical coordinates input file for use with S coordinates. This has been carried out by copying the model code to an offline tool and then modifying it to suppress the use of 3D arrays (to reduce memory usage). 
     14Creation of an offline tool (SCOORD_GEN) to generate a vertical coordinates input file for use with S coordinates. This has been carried out by copying the model code to an offline tool and then modifying it to suppress the use of 3D arrays (to reduce memory usage). The tool has been created in preparation for the removal of the vertical grid definition from the code. The output file should contain all variables that are necessary to restart the model.

    2929The tool has been tested by comparing vertical coordinate output in the mesh_mask file from the AMM12 configuration to the output from the tool. The following variables were compared and were equal to the last bit: 
    30 mbathy, hbatt, hbatu, hbatv, hbatf, e3t_0, e3u_0, e3v_0, e3w_0, gdept_0 
     30mbathy, hbatt, hbatu, hbatv, hbatf, e3t_0, e3u_0, e3v_0, e3w_0, gdept_0. In the case of mbathy the final smoothing stage (removal of isolated grid points) is not included in the tool as this is not unique to S coordinates. It could be added in future though.

    3232Coordinates were generated using Song/Haidvogel 1994, Siddorn/Furner 2012, and tanh functions.
