Configuration

function watermassmatrix(file)
Read and assemble the water-mass matrix.

Arguments

• file: TMI NetCDF or MATLAB file name

Output

• A: water-mass matrix

function watermassmatrix(m::Union{NamedTuple,Vector}, γ::Grid)

Produce water-mass matrix from mass fractions and grid.

Arguments

• m::NamedTuple: collection of MassFractions
• γ::TMI.Grid

Output

• A: sparse water-mass matrix

function circulationmatrix(file,γ)
Read and assemble the circulation matrix from MATLAB.
Transfer to updated x,y,z version

Arguments

• file: TMI MATLAB file name
• γ: TMI grid

Output

• L: circulation matrix in xyz format

function circulationmatrix(file,A,γ)
Read and assemble the circulation matrix from the efficient storage of A and F₀ variables.

Arguments

    function boundarymatrix(file,γ)
Read and assemble the boundary matrix from MATLAB.
Transfer to updated x,y,z version

Arguments

• file: TMI MATLAB file name
• γ: TMI grid

Output

• B: boundary condition matrix

 function surfaceregion(TMIversion::String,region::String,γ::Grid)::BoundaryCondition

Read an oceanographically-relevant surface region from NetCDF file. (Also could be read from mat file.)
Return a BoundaryCondition

 function surfaceregion(TMIversion::String,region::String,γ::Grid)::BoundaryCondition

Read an oceanographically-relevant surface region from NetCDF file. (Also could be read from mat file.)

Return a BoundaryCondition

Version 1: operates on a 2D Float field

function ncurl(TMIversion)
placeholder function to give location (URL) of NetCDF Google Drive input
in the future, consider a struct or Dict that describes all TMI versions.

Arguments

• TMIversion: version of TMI water-mass/circulation model

Output

• url: location (URL) for download

Save TMI configuration to NetCDF format for non-proprietary access

Save grid dictionaries of attributes for writing to NetCDF file

All variable names and attributes. Useful for writing NetCDF files.

Save optimization parameters to NetCDF file)

Future considerations: split into 2 functions

1. read from mat
2. save to nc

Save circulation matrix L to NetCDF file.

Save boundary matrix for transient model to NetCDF file

Put grid properties (Cartesian index) into NetCDF file

function cartesianindex(wet)
Read and assemble the grid coordinates
according to a 3D tracer in x,y,z order

Arguments

Output

• I: 3D Cartesian indices

function cartesianindex(file)
Read and assemble the grid coordinates
according to the legacy MATLAB code (z,y,x order).

Arguments

• file: TMI NetCDF file name

Output

• I: TMI Cartesian index for wet points
