uxarray.grid.utils._get_lonlat_rad_face_edge_nodes(face_nodes_ind, face_edges_ind, edge_nodes_grid, node_lon, node_lat)#

Construct an array to hold the edge lat lon in radian connectivity for a face in a grid.

Parameters:

  • face_nodes_ind (np.ndarray, shape (n_nodes,)) – The ith entry of Grid.face_node_connectivity, where n_nodes is the number of nodes in the face.

  • face_edges_ind (np.ndarray, shape (n_edges,)) – The ith entry of Grid.face_edge_connectivity, where n_edges is the number of edges in the face.

  • edge_nodes_grid (np.ndarray, shape (n_edges, 2)) – The entire Grid.edge_node_connectivity, where n_edges is the total number of edges in the grid.

  • node_lon (np.ndarray, shape (n_nodes,)) – The values of Grid.node_lon.

  • node_lat (np.ndarray, shape (n_nodes,)) – The values of Grid.node_lat, where n_nodes_total is the total number of nodes in the grid.

Returns:

face_edges – Face edge connectivity in Cartesian coordinates, where n_edges is the number of edges for the specific face.

Return type:

np.ndarray, shape (n_edges, 2, 3)

Notes

  • The function assumes that the inputs are well-formed and correspond to the same face.

  • The output array contains the Latitude and longitude coordinates in radian for each edge of the face.
