cf_xarray.vertices_to_bounds#

cf_xarray.vertices_to_bounds(vertices, out_dims=('bounds', 'x', 'y'))[source]#
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).
