polaris.tasks.e3sm.init.topo.remap.get_remap_topo_steps(mesh_name, smoothing=False, include_viz=False)[source]

Get shared steps for computing a mapping file and then remapping bathymetry and ice-shelf topography from a cubed-sphere grid to a global MPAS base mesh. The unsmoothed topography will typically be used to determine coastlines for mesh culling and related masks so that they are independent of smoothing choices (e.g. so mapping files can be reused with different smoothing choices). The smoothed topography will be used for the actual bathymetry, land surface elevation, land-ice pressure, etc.

Parameters:

  • mesh_name (str) – The name of the base mesh to remap topography onto

  • smoothing (bool, optional) – Whether to create a step with smoothing in addition to the step without smoothing

  • include_viz (bool, optional) – Whether to include visualization steps

Returns:

  • steps (dict of str to polaris.Step) – All upstream shared steps plus the steps for remapping topography (without smoothing and optionally with smoothing) as well as, if requested, for visualizing the results, keyed by suggested symlink in tasks.

  • config (polaris.config.PolarisConfigParser) – The shared config options for remapping topography.
