Initial Conditions
  • Interpolated initial data from various coarse-grid driving models (GME, IFS, COSMO-Model) or from the continuous data assimilation stream.
  • Option for user-specified idealized initial fields.
Lateral Boundary Conditions
  • 1-way nesting by Davies-type lateral boundary formulation. Data from several coarse-grid models can be processed (GME, IFS, COSMO-Model).
  • Option for periodic boundary conditions.
Top Boundary Conditions
  • Options for rigid lid condition and Rayleigh damping layer.
Initialization
  • Digital-filter initialization of unbalanced initial states (Lynch et al., 1997) with options for adiabatic (only for the Leapfrog-scheme) and diabatic initialization.
Top Boundary Conditions
  • Options for rigid lid condition and Rayleigh damping layer.
