ICON-D2 microphysically perturbed ensemble simulations including initial and boundary condition uncertainty

The dataset contains hourly outputs of five ICON-D2 ensemble simulations with combined initial and boundary conditions (IBC) and microphysical perturbations. One ensemble dataset consists of 180 ensemble members that are a full combination of 20 IBC, 3 CCN concentration parameters and 3 cloud droplet size distribution shape parameters. The combined impact of microphysical uncertainties can be investigated in the presence of initial and boundary conditions uncertainties in the state-of-the-art numerical weather prediction model.
