Abstract: Internal gravity waves are ubiquitous in the atmosphere and are key components of many aspects of weather and climate. For first time, gravity waves have been measured in a comprehensive manner from near the surface to ~ 100 km altitudes as part of the DEEP propagating gravity WAVE program (DEEPWAVE). DEEPWAVE is a measurement and modeling program centered on New Zealand and focused on providing a new understanding of gravity wave dynamics and impacts from the troposphere through the mesosphere and lower thermosphere. This program employed several research aircraft from a base in New Zealand during June-July 2014. The NSF/NCAR GV was equipped with new remote sensing instruments that provide unique observations of topographically generated gravity waves, as well as waves generated by non-orographic sources. Examples of coupling between the lower and upper levels will be shown using the in situ and remote sensing observations, as well as high-resolution models with deep domains.
