-sensitive tropospheric and stratospheric channels are also assimilated as available from the SSMIS LAS channels and from the Advanced Technology Microwave Sounder (ATMS) on NASA’s Suomi National Polar-Orbiting Partnership ( NPP ) satellite. Our three sensors providing MLT observations, marked in red on the left and right of Fig. 6 , provide 250 000 observations every cycle to the reanalysis with no temporal gaps in coverage, or 7% of the assimilated data volume in the troposphere and stratosphere. While these

analyzes the atmospheric conditions from the troposphere up to the mesosphere during austral winter 2014. We emphasize key circulation features during the DEEPWAVE campaign period and relate them to the climatological mean conditions. The different meteorological conditions are related to observed wave events [intensive observing periods (IOPs) with airborne observations and periods with only ground-based (GB) measurements as listed in Tables 4 and 5 in Fritts et al. (2016) ]. Section 2 provides
