How does heat originate in the atmosphere from the ionization of oxygen by the sun's UV? Author; Rogelio Pérez Casadiego Summary; We all know the explanation of heat in the atmosphere explained with a greenhouse effect, which consists of the retention of infrared radiation emitted by the atoms of the earth by certain gases in the air, this work explains the heat because of the ionization of oxygen by the ultraviolet radiation of the sun, which consists of oxygen (21% of the air) absorbing the entire band of uv radiation from the sun, this ionizes the air, when the air is ionized it becomes a conductor of electricity, increasing its kinetic energy (temperature), its increase means that there will be a greater transfer of heat energy from the air when it comes into contact with everything that is on the surface of the planet. Figure.1 evidence, relationship between the sun's uv and heat on the planet Introduction; The heat on the planet is explained by the gr...
