polaris.tasks.e3sm.init.topo.combine.get_lat_lon_topo_steps

polaris.tasks.e3sm.init.topo.combine.get_lat_lon_topo_steps(component, resolution, include_viz=False)[source]

Get shared combined-topography steps for a latitude-longitude target grid.

The CombineStep (and VizCombinedStep when requested) set default_cached = True in their constructors because they are expensive to produce. Downstream tasks benefit from cached outputs automatically. Tasks that require free-running execution (e.g. standalone combine tasks) should add each returned step’s subdir to self.free_running_steps in their __init__, as LatLonCombineTask does.

Parameters:

  • component (polaris.Component) – The component that the steps will be added to.

  • resolution (float) – The latitude-longitude resolution in degrees.

  • include_viz (bool, optional) – Whether to include the visualization step or not.

Returns:

  • steps (dict of str to polaris.Step) – The combine topo step and optional visualization step, keyed by step name.

  • config (polaris.config.PolarisConfigParser) – The shared config options.
