Satellite remote sensing technique has been continuously showing its power for two decades on monitoring the global gravity wave activities in the lower and upper atmosphere. Depending on the viewing geometry, different satellite instrument is sensitive to different part of the GW spectrum, and we may be able to stitch together the whole picture of GW variability through integrating various satellite observations.

In this presentation, I will first give a brief review from an integrated satellite perspective on global GW behaviors and sources, as well as the how it provides observational constraints on the parameterization of GW sources and momentum fluxes. Then, I will present the diurnal, annual and inter-annual variabilities of GW activity derived from Aura-Microwave Limb Sounder (MLS), Aqua-Atmospheric Infrared Sounder (AIRS), NOAA-Advanced Microwave Sounding Unit A (AMSUA) and the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC). Lastly, with up to 17 years of continuous observations from these satellite instruments, we now have some level of confidence to discuss the GW trend in the stratosphere, which is found closely associated with the change and movement of tropospheric sources under the climate change context.
