The effective column densities that cosmic rays have to pass through from the closer surface to reach each height of the MMSN at 1, 10, and 100 au. The dashed black line is the vertically measured column density that is used in conventional studies for 1 au. The thin horizontal line shows the attenuation length of cosmic rays.
