项目摘要

The Atmospheric-Optics Laboratory at Dalhousie University builds and uses lidar (laser radar) systems for atmospheric research.  Our programme is divided into three main projects: 1) The Dalhousie Raman Lidar observes continental outflow from pollution and forest fires.  The aerosols are used as passive tracers of atmospheric motions and are interpreted with the help of models to gain insight into transport and mixing processes.  2) Atmospheric research will be pursued in the High Arctic at Eureka during the International Polar Year (IPY) and beyond as part of the Canadian Network for the Detection of Atmospheric Change (CANDAC).  A new lidar is being built to study the impact of clouds, aerosols, and water vapour on the radiative environment, which is central to the climate problem.  3) The Phoenix Mars Scout project that will land a lidar on Mars in 2008.  These measurements will provide unique "first-time" information on the vertical distribution of aerosols and clouds in the Martian atmosphere. The Dalhousie Raman Lidar was built from scratch and then used for observations over the past two years.  The measurements have highlighted the regular occurrence of pollution episodes transported from distant sources, and also the injection of aerosols high into the troposphere by forest fires.  We propose to upgrade the lidar by the adding a water vapour profiling capability, which will provide a clearer picture of what is happening in the boundary layer and at tropopause heights.  Data from intensive summertime measurement campaigns will be interpreted with the aid of the FLEXPART Lagrangian particle dispersion model.  Construction of the new lidar for Eureka will be based on our experiences with the Dalhousie Raman lidar, and will have a more extensive set of capabilities.  The work will require travel to the Arctic and contributions to the CANDAC Clouds, Aerosols and Radiation Theme.  Students will be involved in every facet of each of these activities.
达尔豪西大学的大气光学实验室建造并使用激光雷达(激光雷达)系统用于大气研究。我们的方案分为三个主要项目:1)达尔豪西拉曼激光雷达观测污染和森林火灾造成的大陆外流。气溶胶被用作大气运动的被动示踪剂,并在模式的帮助下进行解释,以深入了解传输和混合过程。2)作为加拿大大气变化探测网络的一部分,将在国际极年及以后在北极高纬度地区的尤里卡进行大气研究,正在建造一个新的激光雷达,研究云、气溶胶和水蒸气对辐射环境的影响,3)凤凰号火星探测器项目将于2008年在火星上着陆激光雷达。这些测量将提供独特的“第一次”关于火星大气中气溶胶和云的垂直分布的信息。达尔豪西拉曼激光雷达是从零开始建造的,在过去的两年里用于观测。测量结果突出了经常发生的污染事件从遥远的来源,以及气溶胶注入到对流层的森林火灾。我们建议升级激光雷达,增加水蒸气剖面能力,这将提供边界层和对流层顶高度的更清晰图像。夏季密集测量活动的数据将借助FLEXPART拉格朗日粒子弥散模型进行解释。尤里卡的新激光雷达将基于我们的学生将获得达尔豪西拉曼激光雷达的经验,并将拥有更广泛的能力。这项工作将需要前往北极并为CANDAC云,气溶胶和辐射主题做出贡献。学生将参与这些活动的各个方面。
