The DLR Institut für Physik der Atmosphäre
will contribute to the Deepwave campaign with airborne and ground-based instruments for atmospheric measurements. The DLR Falcon will be stationed at Christchurch airport. A ground-based lidar will be installed at NIWA station in Lauder, Central Otago. Radiosondes will be launched from NIWA station.
The Deepwave campaign is dedicated to the study of atmospheric gravity waves. Gravity waves are excited by the flow over New
Zealands Southern alps and propagate through the atmosphere and are modified by the tropopause. Several in-situ and remote sensing
instruments detect these waves by means of air density or temperature variations in an altitude range between 0 and 120 km at New
Zealands South Island and the surrounding Southern Ocean. Measurements by aircraft will be coordinated with ground-based measurements to study the dynamical and chemical processes in the upper troposphere and lower stratosphere.
