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.We will extend our previous research to determine details of the climatology of stratospheric and mesospheric ozone and the oxygen airglow. This work has provided new information on the ozone profile and distribution in the region of the Antarctic Ozone Hole, and in the NH. The ozone concentrations derived from OSIRIS will be compared with those with those from the sub-millimetre radiometer on Odin. The infrared imager observations will be combined with to determine the H-atom concentration profile. It is expected that this work will provide new information on the transport of hydrogen through the mesosphere and into the thermosphere and its subsequent escape from the planet.We will use the measured height profiles to determine the atmospheric temperature profile. The measurements will also be used to give new information on atmospheric aerosols. We also intend to explore PMC's and polar stratospheric clouds.Finally a major objective is to enhance the training of highly qualified personnel.

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。我们将扩展我们以前的研究，以确定平流层和中间层臭氧和氧气气辉的气候学细节。这项工作提供了关于南极臭氧洞区域和北半球臭氧剖面和分布的新资料。从OSIRIS得到的臭氧浓度将与奥丁上的亚毫米辐射计得到的臭氧浓度进行比较。红外成像仪的观测结果将与确定h原子浓度谱相结合。预计这项工作将提供关于氢通过中间层进入热层以及随后从地球逃逸的新信息。我们将使用测量到的高度分布来确定大气温度分布。这些测量结果还将用于提供有关大气气溶胶的新信息。我们还打算探索PMC和极地平流层云。最后，一个主要目标是加强对高素质人才的培训。
