global_setup

gnomonic_grid(grid_type, lon, lat, np)

Apply gnomonic grid to lon and lat arrays for all tiles. Tiles must then be rotated and mirrored to the correct orientations before use.

This global mesh generation is the way the Fortran code initializes the lon/lat grids and is reproduced here for testing purposes.

Parameters:

Name	Type	Description	Default
grid_type	int	type of grid to apply	required
lon		longitude array with dimensions [x, y]	required
lat		latitude array with dimensions [x, y]	required

global_gnomonic_ed(lon, lat, np)

global_mirror_grid(grid_global, ng, npx, npy, np, right_hand_grid)

Mirrors and rotates all tiles of a lon/lat grid to the correct orientation. The tiles must then be partitioned onto the appropriate ranks. This global mesh generation is the way the Fortran code initializes the lon/lat grids and is reproduced here for testing purposes.
