polaris.mesh.IcosahedralMeshStep.build_subdivisions_cell_width_lat_lon

IcosahedralMeshStep.build_subdivisions_cell_width_lat_lon()

A function for creating cell width array for this mesh on a regular latitude-longitude grid.

Returns:

• subdivisions (int) – The number of subdivisions of the icosahedron to make

• 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)
