Abstract : The middle atmosphere is considered to be the region from 25 to 105 km including the middle and upper stratosphere, mesosphere, and mesosphere-thermosphere transition region up to the turbopause. In the lower portion, up to 80 km, energy inputs and losses are predominantly due to absorption and emission of radiation by ozone, carbon dioxide, and water vapor, with solar absorption by ozone and emission by carbon dioxide playing the major role. Recent computations of heating and cooling rates due to these gases have not led to essential changes, but uncertainties remain. The principle ones are due to uncertainty in the concentrations of water vapor and ozone.
