<!--!introduction!--> Gravity waves (GW) transport energy and momentum from troposphere upwards into the mesosphere, playing an important role connecting the tropospheric weather with the space weather. The NASA Aeronomy of Ice in the Mesosphere (AIM) satellite was launched in 2007 and provided important GW information within PMC near the mesopause region. The newly developed Rayleigh Albedo Abnormally (RAA) data from The Cloud Imaging and Particle Size (CIPS) instrument measure GWs globally outside the PMC region, at the bottom of the mesosphere (~55 km). As part of the international Antarctica Gravity Wave Instrument Network (ANGWIN) project, Utah State University has been running OH All-Sky Imagers (ASI) for more than 10 years at the Australian Davis station (69°S, 78°E) and the British Rothera Station (68°S, 68°W). High quality night time GW images in OH (3,1) intensity are obtained at the top of the mesosphere (~87 km) during each austral winter seasons. In this study, we will utilize GW data ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
