a Strahlungsbilanz serves to balance the radiation exchange of a system with its environment . The radiant fluxes, which leave the system, are up-counted against those, which influence from the outside into the system. This concerns a special form of the energy balance, which is used in particular if other processes of the energy and in particular heat transfer, as for example thermal conduction or convection, to arise and/or. no effect beyond the system borders entfallten. The most important example is the Strahlungsbilanz of the earth.
