xoa.grid.shift(da, shift_dirs, mode='edge', **kwargs)[source]

Shift the grid by an half grid cell along specified dimensions and directions

This is typically useful with Arakawa grids.

Parameters:

da (xarray.DataArray, xarray.Dataset) –
shift_dirs (dict) – Keys are dimension names and values are directions: -1|"left"|"bottom"|"south"|"low"|"west", 1|"right"|"top"|"north"|"high"|"east"
mode (str) – Extrapolation mode at grid edges
