The objectives of the proposed research program are to provide new information of the composition and temperature in the stratosphere and throughout the mesosphere using data from satellite and ground based measurements. 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 also 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 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使用卫星和基于地面的测量结果提供平流层和整个中层层的组成和温度的新信息。这项研究将利用Odin卫星上Osiris仪器可用的数据集的无与伦比的质量，尽管也将使用来自其他卫星（例如ACE/SCISAT，ENVISAT，AURA和TOMS）的数据。 ODIN上的加拿大Osiris仪器在与大气肢体观察结果相关的整个动态范围内提供了高信噪比的测量值。将使用申请人开发的层析成像算法分析Osiris观察结果。该分析程序得出了测量量的垂直和水平结构，以及派生的成分浓度。 Osiris可能的水平和垂直分辨率分别为75公里和1公里。我们将扩展以前的研究，以确定平流层和中层臭氧和氧气气囊的气候细节。这项工作提供了有关南极臭氧孔和NH区域中臭氧轮廓和分布的新信息。将源自奥西里斯的臭氧浓度与ODIN上毫米辐射计的臭氧浓度进行比较。红外成像仪的观察结果将结合使用，以确定H原子浓度曲线。可以预期，这项工作将提供有关氢通过中层运输并进入热层及其随后逃离地球的新信息。我们还将使用测量的高度轮廓来确定大气温度曲线。测量值还将用于提供有关大气气溶胶的新信息。我们打算探索PMC和极地平流层云。最后，一个主要目标是增强对高素质人员的培训。
