(a) Basic schedule, 1-to-1 diffusion step to dynamical timestep mapping
(b) Auxiliary, additional diffusion steps (here,  $k = 3$ ) map uniformly to  $(0,1)$
Figure 9: Exemplary sampling trajectories of two different schedules for mapping diffusion steps,  $n$ , to interpolation timesteps,  $i_n$ . For convenience, Fig. 9a is a copy of Fig. 2. The schedules are illustrated using a horizon of  $h = 4$ . The black lines represent forecasts performed by the forecaster network,  $F_{\theta}$ . The first forecast is performed based on the initial conditions,  $\mathbf{x}_0$ . The blue lines represent the subsequent temporal interpolations performed by the interpolator network,  $\mathcal{I}_{\phi}$ .
