          ! IFS currently sets the half-level temperature at the surface to be
          ! equal to the skin temperature. The radiation scheme takes as input
          ! only the half-level temperatures and assumes the Planck function to
          ! vary linearly in optical depth between half levels. In the lowest
          ! atmospheric layer, where the atmospheric temperature can be much
          ! cooler than the skin temperature, this can lead to significant
          ! differences between the effective temperature of this lowest layer
          ! and the true value in the model.
          ! We may approximate the temperature profile in the lowest model level
          ! as piecewise linear between the top of the layer T[k-1/2], the
          ! centre of the layer T[k] and the base of the layer Tskin.  The mean
          ! temperature of the layer is then 0.25*T[k-1/2] + 0.5*T[k] +
          ! 0.25*Tskin, which can be achieved by setting the atmospheric
          ! temperature at the half-level corresponding to the surface as
          ! follows:
