Description
Summary:<!--!introduction!--> Sudden stratospheric warming (SSW) events have a significant impact on stratospheric ozone in the Arctic region. This study uses GROMOS-C radiometer measurements and MERRA-2 data, and Aura-MLS observations to investigate the ozone variability over Svalbard (79°N, 12°E) for SSW events between 2016 and 2022 and examines the potential role of stratospheric ozone in connection to the mesospheric tides enhancement of the migrating semidiurnal (SW2) tide reported for such events. GROMOS-C measurements show good agreement with MERRA-2 simulation and Aura-MLS observations in the middle stratosphere during highly altered dynamics of SSW. Here we focus on the stratospheric ozone anomaly associated with the onset of a major SSW at polar latitudes. Furthermore, we extract the mesospheric semi-diurnal tide (SDT) and diurnal tide (DT) observed in the zonal and meridional winds recorded by a nearby meteor radar over Svalbard (79°N, 12°E). We analyze the anomaly variations in stratospheric ozone ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
