The most frequent type of ground or surface-based temperature inversion is the one produced by terrestrial radiation usually on a clear, still night. Temperature inversion refers to the increase in temperature brought about by the rise in altitude. On the other hand, terrestrial radiation refers to the radiation naturally emitted by radioactive materials present on Earth. Among these are radon, thorium, and uranium.
