It is important to state here that highly varying wave saturation and dissipation processes occurring at mesospheric altitudes may lead this relationship to vary.
(1) Mesospheric airglow data show large variability in the gravity wave amplitudes.
The satellite observed a second northern season of Polar Mesospheric
Clouds (PMCs), which are the Earth's highest clouds.
Extra-long period (20-40 days) oscillations in the mesospheric

Gardner's team found that the mesospheric
clouds over the South Pole were, on average, at an altitude of 85.5 km at the peak of summer.

Data from pressure-modulated infrared sounders [selective chopper radiometer (SCR) and pressure modulator radiometer (PMR); Table 1] and one limb-viewing infrared sounder [stratospheric and mesospheric
sounder (SAMS)] were curated by a project funded by the U.K.

In the winter polar vortices, measurements of several additional tracers with production or loss in the mesosphere would allow information about mesospheric
influence and mass flux into the stratosphere.
