CEDAR: Observational and Numerical Studies of the Momentum Budget of the Extratropical Summertime Mesosphere

PI将联合收割机结合高层大气研究卫星和雷达数据，以获取有关中层和低热层（MLT）环流和动量源/汇的信息。 通过将雷达和风成像干涉仪的测量结果与高分辨率多普勒成像仪的风相结合，PI可以直接从全球风观测中确定MLT的输送环流。 此外，改进对重力波驱动的估计将有助于改进对MLT区域和平流层环流系统的模拟。 最后，这项研究的结果对于根据热数据估计中层风很重要。

The PI will combine the Upper Atmosphere Research Satellite and radar data to gain information on circulations and momentum sources/sinks in the mesosphere and lower thermosphere (MLT). By properly combining radar and Wind Imaging Interferometer measurements with High Resolution Doppler Imager winds, the PI can determine the MLT transport circulation directly from global wind observations. In addition, improved estimates of gravity-wave driving will allow improved simulations of circulation systems in the MLT region and at stratospheric levels. Finally, results from this research will be important for estimations of mesospheric winds from thermal data.***
