TARDIS (Time and Relative Dimension(s) in Space) is module to travel an iris cube.
No docs at the moment... Move along!
Depending on which model is used, the horizontal coordinate of the output data may be on a regular, curvilinear, or unstructured (e.g., triangular) grid, while the vertical coordinate may be on a uniform or stretched grid with a number of different possibilities (e.g., sigma, sigma-over-z, s-coordinate, isopycnal). Ocean modelers spend way to much time on data manipulation tasks just to read the data!!!
Tardis complements the iris cube with some extra methods to make that task even easier.
