The DEEPWAVE Program employed a suite of airborne and ground-based measurements to quantify gravity wave (GW) dynamics and effects from the ground to the upper mesosphere in unprecedented detail. Coordinated observations were made over the South Island, New Zealand, and the surrounding Oceans during June and July 2014, providing an exceptionally rich multi-instrument data set. This presentation highlights exciting new airborne and ground-based results obtained during the campaign using an Advanced OH Mesospheric Temperature Mapper (AMTM), which creates high-quality intensity and temperature maps of a broad spectrum of mesospheric GWs. Two AMTM’s were employed, one wide field (120°) instrument sited at the NIWA Observatory, Lauder (45°S), on the South Island, and one medium field (80° x 60°) system mounted in the NSF GV Gulfstream aircraft. The airborne image measurements were also supplemented by two side viewing IR OH imagers providing large field, ~900 km cross-track, GW maps. Together they formed part of a comprehensive measurements capability including airborne Rayleigh and Na lidars, dropsondes, ground-based Rayleigh lidar, all-sky imagers and wind measurements. This presentation focus on two important findings (a) discovery and quantification of large amplitude, mesospheric mountain waves including their intermittent wave breaking signatures, and (b) novel measurements of large-field coherent open-ocean mesospheric GW and their remarkably similar wave signatures in the stratosphere, using AIRS satellite data and model forecasting.
