The objectives of the proposed research program are to provide new information on the composition and temperature in the stratosphere and throughout the mesosphere using data from satellite and ground based instruments. This research will take advantage of the unparalleled quality of the data-set that is available from the OSIRIS instrument on the Odin satellite, although data from other satellites such as ACE/SciSat, Envisat, Aura and TOMS will also be used. The Canadian OSIRIS instrument on Odin provides high signal-to-noise ratio measurements over the entire dynamic range associated with observations of the atmospheric limb. The OSIRIS observations will be analyzed using the tomographic algorithms developed by the applicant. This analysis procedure yields both the vertical and horizontal structure of the measured quantities, and the derived constituent concentrations. The horizontal and vertical resolutions possible with OSIRIS are 75 km and 1 km respectively.

拟议的研究计划的目标是利用卫星和地面仪器的数据，提供关于平流层和整个中间层的成分和温度的新信息。这项研究将利用奥丁卫星上的OSIRIS仪器提供的无与伦比的数据集，尽管也将使用ACE/SciSat、Envisat、Aura和TOMS等其他卫星的数据。奥丁号上的加拿大OSIRIS仪器提供了与大气边缘观测相关的整个动态范围的高信噪比测量。OSIRIS观测数据将使用申请人开发的层析成像算法进行分析。这个分析过程产生了测量量的垂直和水平结构，以及衍生的成分浓度。OSIRIS的水平和垂直分辨率分别为75公里和1公里。
