The proposed research program will provide new information on the atmospheric state vectors (particularly composition and temperature) in the upper stratosphere, throughout the mesosphere and into the lower thermosphere using data from satellites. We intend to take advantage of the data-set from the OSIRIS instrument - a spectrograph and imager - on the Odin satellite. The data inversion methods will use both the tomographic algorithms developed by the University of Saskatchewan group as well new approaches for weak emissions embedded in a strong solar background. These analysis procedures allow both the vertical and horizontal structure of the measured quantities to be retrieved.

拟议的研究计划将利用卫星数据提供关于平流层上层、整个中间层和低层热层的大气状态向量（特别是成分和温度）的新信息。我们打算利用奥丁卫星上的光谱仪和成像仪OSIRIS仪器的数据集。数据反演方法将使用萨斯喀彻温大学小组开发的层析成像算法以及嵌入在强太阳背景中的弱辐射的新方法。这些分析程序允许检索测量量的垂直和水平结构。
