includes the Sensbile Heat (H) the outgoing black body radiation (in this case infrared radiation) or only the the transfer of energy via conduction when the airmolecules collide with the surface? Or in otherway is Rn the net of incoming sunlight minus the outgoing infrared radiation? If so, why would you work with this Rn in an energy balance model? Would it not better to R_full_incoming_sunlight and out R_infrared_surface?
