Description
A new three-dimensional model of the solar photosphere is presented in
this paper and made publicly available to the community. This model has
the peculiarity of having been obtained by inverting
spectro-polarimetric observations, rather than by using numerical
radiation hydrodynamical simulations. The data used here are from the
spectro-polarimeter onboard the Hinode satellite, which routinely
delivers Stokes I, Q, U, and V profiles in the 6302 Å spectral
region with excellent quality, stability, and spatial resolution
(approximately 0.3''). With this spatial resolution the major granular
components are resolved, which implies that the derived model needs no
micro- or macroturbulence to properly fit the widths of the observed
spectral lines. Not only does this model fit the observed data used for
its construction, but it can also fit previous solar atlas observations
satisfactorily.

Magnetic fields pervade all astrophysical plasmas and govern most of the variability in the Universe at intermediate time scales. They are present in stars across the whole Hertzsprung-Russell diagram, in galaxies, and even perhaps in the intergalactic medium. Polarized light provides the most reliable source of information at our disposal for the
