Now you could run a SpeedyWeather simulation, and analyse the [NetCDF output](@ref)
but that comes with several issues related to accuracy

- If you use a reduced grid for the simulation, then the output will (by default) be
interpolated on a full grid. This interpolation comes introduces an error.

- Computing integrals over gridded data on the sphere by weighting every grid point
according to its area is not the most accurate numerical integration.

- Computing gradients over gridded data comes with similar issues. While our
[RingGrids](@ref) are always equidistant in longitude, they are not necessarily
in latitude.

The first point you can avoid by running a simulation on one of the full grids that
are implemented, see [SpectralGrid](@ref). But that also impacts the simulation
