DEEP propagating gravity WAVE (DEEPWAVE) is an interdisciplinary project addressing the propagation and effects of gravity waves (GW) extending from their generation in the troposphere to their breakdown in the mesosphere and lower thermosphere (MLT). The project is designed by experts on the MLT and the lower atmosphere. These research communities have not worked closely together before, but a coupled approach is required to address these dynamics in a comprehensive and consistent manner. GWs strongly influence the dynamics and climate throughout the atmosphere. DEEPWAVE will provide a more complete understanding of GW generation, propagation, breakdown, and energy and momentum transport in the presence of large topography, cyclones, and strong wind shears than has been possible previously. At the core of the project is a 6-week deployment of the NSF Gulfstream V (GV) research aircraft to Christchurch in June and July 2014. The GV flights will take place over mountain wave locations over and downwind of New Zealand, Tasmania, and islands in the Southern Ocean as well as the southern circumpolar jet that is an additional strong GW source. Recent satellite remote sensing has identified this region as a primary global "hotspot" of GWs reaching high altitudes. Using the GV in situ instruments, dropsondes, and three new airborne remote sensing instruments, nearly the full vertical propagation path of GWs can be observed. The GV will fly at altitudes from 9-13 km with in situ instruments observing the structure and fluxes of GWs up to ~18 km. On the GV, high-power Rayleigh and Na resonance lidars and an advanced mesospheric temperature mapper (AMTM) will map out GW structures from ~15 to 100 km. These state-of-the-art measurements will be supplemented by ground-based balloon and remote sensing instruments. This 4-year research program includes DEEPWAVE measurements in 2014, and extensive analysis efforts and associated modeling to quantify the observed dynamics thereafter. All DEEPWAVE data will be made available in a timely fashion. In addition to the investigators supported by this collaborative award, participants supported by NRL as well as international collaborators from New Zealand, Australia, Canada, Germany and the UK will be closely involved in the DEEPWAVE project.

深度引力波（深浪）是一个跨学科的项目，该项目解决了从对流层中的产生延伸到中层和较低热层（MLT）中的重力波（GW）的传播和影响。该项目是由MLT和较低气氛的专家设计的。这些研究社区以前并没有紧密合作，但是需要采用耦合的方法来以全面和一致的方式解决这些动态。 GWS强烈影响整个大气中的动态和气候。 DeepWave将在存在大地形，旋风和强风剪的情况下对GW的产生，繁殖，能量和动量运输提供更全面的了解。该项目的核心是NSF Gulfstream V（GV）研究飞机在2014年6月至基督城进行了为期6周的部署。GV航班将在新西兰，塔斯马尼亚州和南部岛屿的山区浪潮中进行，以及南部大洋以及南部千里射流的山脉以及其他强大的GW源。最近的卫星遥感已将该区域确定为GWS的主要全球“热点”，达到了高海拔高度。 可以使用GV，Dropsondes和三种新的空中遥感仪器，几乎可以观察到GWS的完整垂直传播路径。 GV将在9-13公里的高度上飞行，现场仪器观察GWS的结构和通量，最高约18公里。在GV上，高功率雷利和Na共振激光痛以及高级的Mesospheric温度映射器（AMTM）将绘制约15至100 km的GW结构。这些最先进的测量结果将通过地面气球和遥感仪器补充。 这项为期4年的研究计划包括2014年的深浪测量以及广泛的分析工作和相关的建模，以量化此后观察到的动态。所有DeepWave数据将及时提供。除了获得合作奖的支持者之外，NRL的支持以及来自新西兰，澳大利亚，加拿大，德国和英国的国际合作者的参与者将密切参与DeepWave项目。
