Infrared radiation is associated with heat energy.
Insolation - solar radiation on the surface of the Earth. This term has been generally replaced by solar irradiance because of the confusion of the word with insulation . Inversion - typically, a temperature inversion, or a zone in the atmosphere in which the temperature increases with altitude, instead of the expected decrease. In general, an inversion is any reversal of the normal trend of the property of an atmospheric substance with respect to altitude. Interferometer - an instrument for determining the spectral distribution of irradiance.
