propagation behavior. 2. Instrument description Over the years, DLR’s coherent DWL system has been successfully deployed in several ground-based and airborne field campaigns targeting various objectives, such as measuring aircraft wake vortices ( Köpp et al. 2004 ), aerosol optical properties ( Chouza et al. 2015 ), and horizontal wind speeds over the Atlantic Ocean as input data for assimilation experiments ( Weissmann et al. 2005b ). A general overview of DWL applications for atmospheric research and an

dynamics, and their significant dependence on GW sources and the environments through which they propagate, pose major challenges for their parameterizations in global weather and climate models. Scientific interests and societal needs have motivated many previous studies of GWs from the stable boundary layer and troposphere, through the stratosphere and mesosphere, and into the thermosphere. Among the more important of these are the following: GWs pose hazards to people and property; examples include

NGV’s nominal ~10 h maximum. Since all planned NGV flights for DEEPWAVE were to occur at night due to onboard active and passive optical remote sensors ( Fritts et al. 2016 ), nominal takeoff was at ~0600 UTC (just after dusk at 1800 LT) with nominal landing in Christchurch at ~1600 UTC. Fig . 7. AIRS NRT brightness temperature perturbations from descending overpasses on 10 Aug 2013 in (a) the 100 hPa and (b) the 2.5 hPa channel. The pink curve shows the hypothetical “dry run” NGV flight track on
