Query: 3D Model Atmospheres of Red Giant Stars   We provide a brief overview of the modelling of the atmospheres of red giant
stars with the 3D radiation-hydrodynamics code CO5BOLD. We emphasize aspects
where 3D modelling provides additional insight beyond standard hydrostatic 1D
models, and comment on present modelling challenges.
