Abstract

Context. Detailed 3D-simulations of magneto-convection in the solar photosphere are now available. They intend to capture the main physical mechanisms at play in this boundary layer, where complex physical phenomena, such as convective overshooting and small scale magnetic dynamo take place. But numerical limitations in spatial resolution and in box-size are likely to affect the description of some relevant physical scales, so simulations need to be compared to independent observations allowing us to explore the full height range of the photosphere.
