We studied the propagation of acoustic gravity waves (AGW) in non-isothermal, wind-free atmosphere taking into account viscosity and heat conduction. We found that under such conditions the maximum AGW amplitude corresponds to an approximate height of 90\,km (mesopause level). The temperature gradient on height is the principal source of wave dumping. We found changes of temperature and pressure due to AGW damping that corresponds to mesopause levels.
