Based on a novel 3-D Stokes profile inversion (Zeeman-Tomography), which utilizes high-spatial, mixed-polarity magnetoconvection simulation data, we have investigated a number of quiet regions in the solar photosphere observed by Hinode/SOT. Zeeman-Tomography is a unique technique to reconstruct, on a geometric height scale, the 3-dimensional structure of various atmospheric quantities from observed Stokes profiles. Using spectropolarimetric observations from Hinode/SOT our Zeeman-Tomography approach allowed us to determine the spatial structure of the temperature, line-of-sight (LOS) velocity as well as the LOS and horizontal component of the magnetic field, for a photospheric layer of 500 km in height and a field-of-view of 12.000x12.000 km. From the 3-D representation of the photospheric region many small scale flux tube like structures can be identified in the lower photosphere with a maximum field strength of several hundred Gauss. The majority of these structures rapidly lose their strength and coherence with height and only a few stronger flux structures can retain a significant field strength to the upper photosphere. Moreover, we are able to estimate the height dependent probability density function (pdf) of the magnetic field strength. The pdf exhibit a rapid decline of the strong field part of the distribution with height which goes along with a decline in the overall (LOS) magnetic flux density. After a brief introduction of our Zeeman-Tomography approach, I will discuss how these topological and empirically derived findings fit into the current picture of the quiet Sun magnetism.
