The amplitude discrepancy between solar limb darkening and Doppler measurements in the five-minute range, suggests the possible existence of Earth's atmosphere oscillations. Recent aeronomical observations add strong evidence to this point of view. A possible explanation of the mysterious 160-min period is presented as a direct consequence. Short period oscillations are another one. Slight discrepancies between Doppler data and between those with theoretical calculations could be also explained in the same way.
