.. py:class:: ThermalSurface(full_config: Config)

   Bases: :py:obj:`isofit.surface.surface_multicomp.MultiComponentSurface`


   A model of the surface based on a Mixture of a hot Black Body and
   Multicomponent cold surfaces.


   .. py:attribute:: idx_surface


   .. py:attribute:: surf_temp_ind


   .. py:attribute:: emissive
      :value: True



   .. py:attribute:: n_state


   .. py:attribute:: emissivity_for_surface_T_init


   .. py:attribute:: surface_T_prior_sigma_degK


   .. py:method:: xa(x_surface, geom)

      Mean of prior distribution, calculated at state x.  We find
      the covariance in a normalized space (normalizing by z) and then un-
      normalize the result for the calling function.



   .. py:method:: Sa(x_surface, geom)

      Covariance of prior distribution, calculated at state x.



   .. py:method:: fit_params(rfl_meas, geom, *args)

      Given a reflectance estimate, find the surface reflectance



   .. py:method:: dlamb_dsurface(x_surface, geom)

      Partial derivative of Lambertian reflectance with respect to state
      vector, calculated at x_surface.



   .. py:method:: calc_Ls(x_surface, geom)

      Emission of surface, as a radiance.



   .. py:method:: dLs_dsurface(x_surface, geom)

      Partial derivative of surface emission with respect to state vector,
      calculated at x_surface.



   .. py:method:: drdn_dsurface(rho_dif_dir, drfl_dsurface, dLs_dsurface, s_alb, t_total_up, L_tot, L_down_dir)

      Derivative of radiance with respect to
      full surface vector



   .. py:method:: summarize(x_surface, geom)

      Summary of state vector.
