cf_xarray.vertices_to_bounds

cf_xarray.vertices_to_bounds(vertices, out_dims=('bounds', 'x', 'y'))

Convert vertices to CF-compliant bounds.

There are 2 covered cases:

• 1D coordinates, with vertices of shape (N+1,), converted to bounds of shape (N, 2)

• 2D coordinates, with vertices of shape (N+1, M+1). converted to bounds of shape (N, M, 4).

Parameters:

verticesDataArray

The vertices to convert. Must be of shape (N + 1) or (N + 1, M + 1).

out_dimsSequence[str],

The name of the dimension in the output. The first is the ‘bounds’ dimension and the following are the coordinate dimensions.

Returns:

DataArray

Either of shape (2, N) or (4, N, M).
