polaris.ocean.vertical.zlevel.compute_z_level_resting_thickness

polaris.ocean.vertical.zlevel.compute_z_level_resting_thickness(layerThickness, ssh, bottomDepth, minLevelCell, maxLevelCell)

Compute z-level resting thickness by “unstretching” layerThickness based on ssh and bottomDepth

Parameters:

• layerThickness (xarray.DataArray) – The thickness of each layer (level)

• ssh (xarray.DataArray) – The sea surface height

• bottomDepth (xarray.DataArray) – The positive-down depth of the seafloor

• minLevelCell (xarray.DataArray) – The zero-based index of the top valid level

• maxLevelCell (xarray.DataArray) – The zero-based index of the bottom valid level

Returns:

restingThickness (xarray.DataArray) – The thickness of z-star layers when ssh = 0
