CEDAR: Investigations of Gravity Wave Coupling Between the Mesosphere and Thermosphere in the Southern Hemisphere

本项目的目的是研究南方中纬度地区大气重力波的发生、传播特征和耦合过程，从对流层到中间层和低层热层。新西兰约翰山天文台目前安装了一台多波长全天空成像仪，将用于记录大气层重力波的活动。第二台成像仪将安装在约翰山以南更远的奥塔哥兰黛的一个野外站，以在DEEPWAVE期间提供更大的覆盖范围，并尽量减少冬季战役期间任何地点的恶劣天气条件。约翰山仪器与其他与中间层和热层观测有关的地面仪器位于同一位置。同一位置的多诊断测量将包括由两台Fabry-Perot光谱仪获得的中间层和热层风和温度，以及由流星雷达系统获得的中间层风廓线，来自电离层探空仪的电子密度廓线，以及SABER温度和OH发射廓线。这些测量结果也将有助于2014年6 - 7月在新西兰进行的DEEPWAVE油田项目。数据将通过波士顿大学的一个网站以及CEDAR和MADRIGAL数据库传播。该项目将与来自新西兰的科学家合作进行。

The goal of this project is to investigate the occurrence, propagation characteristics, and coupling processes of atmospheric gravity waves in the Earth's atmosphere, from the troposphere up to the mesosphere and lower thermosphere, at Southern mid-latitudes. A multi-wavelength all-sky imager currently resides at the Mount John Observatory in New Zealand and will be used to record meospheric gravity wave activity. A second imager will be installed at a field station further to the south of Mount John, at Lauder, Otago, to provide greater coverage during DEEPWAVE and to minimize poor weather conditions at either location during the winter campaign period. The Mount John instrument is co-located with other ground-based instrumentation relevant to mesospheric and thermospheric observations. The co-located multi-diagnostic measurements will consist of mesospheric and thermospheric winds and temperatures obtained by two Fabry-Perot spectrometers and mesospheric wind profiles obtained by a meteor radar system, electron density profiles from an ionosonde, and SABER temperature and OH emission profiles. These measurements will also contribute to the DEEPWAVE field project which will take place in New Zealand in June-July 2014. Data will be disseminated via a website at Boston University and the CEDAR and MADRIGAL databases. The project will be carried out in collaboration with scientists from New Zealand.
