The ionosphere is the layer of the atmosphere that reflects radio waves. This effect is caused by the ionization, or electrical charging, of the gas particles present in the upper atmosphere by X-rays and ultraviolet rays emitted by the sun.
Radiation Balance for Both Earthâs Surface and Atmosphere. The incoming solar radiation is absorbed at Earthâs surface (51 units) and by the atmosphere and clouds (19 units). This is balanced by the infrared radiation emitted from Earthâs surface (6 units) and from the atmosphere (64 units) which are both lost to space.
