regionate.grid_conform.get_region_boundary_grid_indices

regionate.grid_conform.get_region_boundary_grid_indices(lons, lats, grid)

Find boundary coordinates and grid indices that approximate a polygon.

Parameters:

• lons (list or np.ndarray of longitudes)

• lats (list or np.ndarray of latitudes)

• grid (xgcm.Grid instance)

Returns:

• (i_c, j_c, lons_c, lats_c, lons_uv, lats_uv)

• i_c (“X”-axis grid indices of corner points)

• j_c (“Y”-axis grid indices of corner points)

• lons_c (longitudes of corner points)

• lats_c (latitudes of corner points)

• lons_uv (longitudes of (u,v) velocity faces)

• lats_uv (latitudes of (u,v) velocity faces)
