近年来，航空部门对测量云冰颗粒总质量和质量分布的兴趣有所增加，因为商用飞机上的单喷气发动机和多喷气发动机在使用中失去动力的事件越来越多，通常是在深对流附近飞行时(Lawson等人)。1998年，Mason et al.2006，Pasztor，2008)。飞行员报告、飞行数据记录器数据和一些工业试飞数据强烈表明，这些事件可能与发动机摄入高冰水有关。这类活动对业界和公众都有明显的成本和安全影响。最近，加拿大国家研究委员会(NRC)一直致力于创建一种冰粒模拟设备，用于在高冰水含量(IWC)条件下测试喷气发动机和/或发动机部件。冰粒是通过刨碎冰块或使用研磨机产生的。加拿大环境部正在与NRC合作，对隧道中产生的IWC数量进行校准。通过测量隧道上IWC的相对轮廓，并知道输送到隧道中的冰量，就有可能提供隧道内任何位置IWC的绝对估计。
In recent years, aviation sector interest in the measurement of cloud ice particle total mass and mass distribution has grown due to an increasing number of in-service single and multiple jet engine power-loss events on commercial aircraft usually when flying in the vicinity of deep convection (Lawson et al. 1998, Mason et al. 2006, Pasztor, 2008). Pilot reports, flight data recorder data, and some industry flight test data strongly indicate that the events are probably related to the ingestion of high ice water content into the engines. Such events have obvious cost and safety implications to the industry and the public. Recently, the National Research Council of Canada (NRC) has been working to create an ice particle simulation facility for testing jet engine and/or engine components in high ice water content (IWC) conditions. Ice particles are created by shaving ice blocks, or by using a grinding mill. Environment Canada is collaborating with NRC on the calibration of the IWC quantities produced in the tunnel. By measuring the relative profile of IWC across the tunnel, and knowing the amount of ice delivered into the tunnel, it is possible to provide an absolute estimate of the tunnel IWC at any location across the tunnel.
