A function for creating cell width array for this mesh on a regular latitude-longitude grid. The default method use constant resolution by setting the cell_width config option in the [spherical_mesh] section. Subclasses should override this function if a more complex cell-width map is needed.


  • cell_width (numpy.ndarray) – m x n array of cell width in km

  • lon (numpy.ndarray) – longitude in degrees (length n and between -180 and 180)

  • lat (numpy.ndarray) – longitude in degrees (length m and between -90 and 90)
