The temperature and velocity field within granular cells has been studied by solving the nonequilibrium inverse radiative transfer problem using neutral iron line λ ≈ 523.4 nm profiles. The results are the following: the temperature and velocity maxima do not always coincide and the maxima can be shifted towards the boundaries in large granules; the temperature inversion takes place. The temporal changes of the shapes of the reconstructed distributions of the temperature and the vertical velocity on the subgranulation scales has been investigated. Also the effect of finite resolution on spatial variations of the velocities and temperaturein the solar photosphere has been estimated.
