Which factor should be included in a model of energy flow into the atmosphere?

One factor that should be included in a model of energy flow into the atmosphere is the solar radiation. Solar radiation is the primary source of energy for the Earth's atmosphere. It includes both the visible light and the non-visible ultraviolet and infrared radiation emitted by the Sun. This solar radiation is absorbed by the Earth's atmosphere, which then undergoes different processes of energy transfer, such as conduction, convection, and radiation. Hence, incorporating solar radiation as a factor is crucial for accurately modeling the energy flow into the atmosphere.
