Atmospheric aerosols (sometimes referred to as Particulate Matter) originate from numerous natural sources including sea spray, (sea salt particles), volcanic eruptions, dust storms, and forest fires. Emissions of particles from industry including power generation, domestic heating, and combustion processes in the transport sector are also important and growing sources. Describing the distribution and transport of aerosols is critically important to understanding Global Climate Change (particles have both direct (radiative), and indirect (cloud microphysics) impacts on Global climate) as well as identifying impacts on air quality, visibility, aviation, and human health at the local and regional scales. This proposed research focuses on the environmental measurement of particulate matter using the relatively novel technology of mini-micro-pulse LiDAR (MMPL). This remote sensing technology is typically used in upward pointing mode to examine transport of aerosols at large scales and through a depth of 10-12 km in the lower atmosphere. Here, the focus is on measurements near ground (the so-called boundary layer) and at small scales (eg. cities, highways) that are of direct relevance to the development of sound air quality management strategies that protect environmental and human health in Canada. The research includes two main threads. Firstly,

大气气溶胶（有时称为颗粒物）来源于许多自然来源，包括海水喷雾（海盐颗粒），火山爆发，沙尘暴和森林火灾。来自工业的颗粒排放，包括发电、家庭供暖和运输部门的燃烧过程，也是重要的和不断增长的来源。描述气溶胶的分布和传输对于理解全球气候变化（粒子对全球气候有直接（辐射）和间接（云微物理）影响）以及确定对空气质量，能见度，航空和人类健康的影响至关重要。这项研究的重点是使用相对新颖的微小脉冲激光雷达（MMPL）技术对颗粒物进行环境测量。这一遥感技术通常以向上指向的方式使用，以检查大尺度和低层大气中10-12公里深度的气溶胶迁移情况。在这里，重点是在近地面（所谓的边界层）和小尺度（例如，城市、高速公路），这些都是直接关系到健全的空气质量管理战略，保护环境和人类健康在加拿大的发展。本研究包括两条主线。第一、
