• Keep documentation updated with new releases.
• Format that can be referenced in publications.
• Distributed with model code.
• Combined documentation for formulation and implementation would be useful.
• Tutorial most useful for getting started.
• Scientific performance can be covered in peer reviewed articles.

As many of us now work with storm resolving resolutions, we feel a lack of documentation for the Sapphire Physics. Such a documentation should cover:

• Turbulent diffusion
  • Vertical diffusion for storm resolving simulations
  • Smagorinsky diffusion for large eddy simulations
• Surface properties
  • Land domain: JSBACH
  • Ocean domain: prescribed with or without ice, mixed layer, or coupled
• Cloud processes
  • Saturation adjustment
  • Cloud microphysics (single moment “graupel”)
  • Cloud cover
• Radiation
  • PSRAD scheme
  • RTE-RRTMGP scheme
  • Insolation: orbit, zenith angle, solar irradiance
  • Surface properties: albedo, emissivity
  • Atmospheric composition: gases, clouds optical properties and overlap, aerosol distributions and optical properties
• Coupling of processes: dynamics to physics, and between physical processes
• Infrastructure available/needed for physics

Further discussion is needed. No decision have been taken so far.
