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.

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环流和动量源/汇的信息。 通过将雷达和风成像干涉仪测量与高分辨率多普勒成像仪风相结合，PI可以直接从全球风观测中确定MLT输送环流。 此外，改进对重力波驱动的估计可以改进对MLT区域和平流层环流系统的模拟。 最后，这项研究将导致根据热数据估计中层风。
