earth's radiation balance
21Cyclotron radiation — is electromagnetic radiation emitted by moving charged particles deflected by a magnetic field. The Lorentz force on the particles acts perpendicular to both the magnetic field lines and the particles motion through them, creating an acceleration …

25Greenhouse effect — The Greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs infrared radiation. [ [http://www.ipcc.ch/pdf/assessment report/ar4/syr/ar4 syr… …
26Greenhouse gas — Simple diagram of greenhouse effect. A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] …
