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

结合高层大气研究卫星和雷达数据，PI获得关于中间层和低热层(MLT)的环流和动量源/汇的信息。通过将雷达和风成像干涉仪的测量与高分辨率多普勒成像仪的风适当地结合在一起，PI可以直接根据全球风观测确定MLT输送环流。此外，改进了对重力波驱动的估计，从而改进了对MLT区域和平流层水平的环流系统的模拟。最后，这项研究将导致根据热力数据估计中间层风。

Combining the Upper Atmosphere Research Satellite and radar data, the PI gains 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 allows improved simulations of circulation systems in the MLT region and at stratospheric levels. Finally, the research will result in estimations of mesospheric winds from thermal data.
