Line-of-sight velocities taken directly from horizontal slices of the simulations at different heights. The left column shows the 6 km simulation, the middle column shows the 12 km simulation, and the right column shows the 23 km simulation. The top row corresponds to a height of 0.66 Mm, i.e., in the low chromosphere, while the bottom row corresponds to a height of 0.16 Mm, i.e., in the photosphere. It is important to note that here, and in all subsequent colormaps, we only show a quarter of the full simulation extent in order to more easily see fine details.
