Abstract
We present Rayleigh density temperature lidar temperature measurements of the stratosphere and mesosphere that extends over 87 nights from September 2018 to April 2022 made at Chatanika, Alaska (65°N, 147°W). We highlight the wintertime measurements, where sudden stratospheric warming (SSW) events occurred in 2019 and 2021. We focus on the meteorology of the polar stratospheric vortex, the Aleutian anticyclone, the planetary wave activity, and the mean winds. The temperature profiles measured in January and February 2019 reflect the evolution of the SSW and the recovery of the circulation with the disappearance of the stratopause, the appearance near isothermal temperature profile, and the return to a conventional stratopause.
