- `topology`: Tuple of topologies (`Flat`, `Bounded`, `Periodic`) for each direction. The vertical
`topology[3]` must be `Bounded`, while the latitude-longitude topologies can be
`Bounded`, `Periodic`, or `Flat`.
`Bounded`, `Periodic`, or `Flat`. If no topology is provided then, by default, the
topology is (`Periodic`, `Bounded`, `Bounded`) if the latitudinal extent is 360 degrees
or (`Bounded`, `Bounded`, `Bounded`) otherwise.

- `precompute_metrics`: Boolean specifying whether to precompute horizontal spacings and areas.
Default: `true`. When `false`, horizontal spacings and areas are computed
