项目摘要

Lidar measurements of wind, water vapour, ozone, aerosol or clouds are key components of a significant number of planned HALO missions. Although these missions have differing scientific goals and utilise different combinations of lidars and other instruments, a common focus on extratropical weather systems and the common reliance on lidar data provides unique opportunities to develop methods and obtain scientific results beyond what is possible in the context of the individual missions. The aim of HALO-LIDAR is to exploit these synergies by addressing a subset of scientific goals that span several HALO missions, and to develop methods for analysing physically relevant quantities based on combinations of data from lidars and other instruments. The scientific goals centre around measurements of transport and fluxes, especially of water vapour, upstream of developing North Atlantic cyclones, of cirrus properties in their warm sector, and around the identification of related key physical processes through combinations of constituent measurements. Model data from associated projects, especially ensemble simulations, will be exploited to quantify uncertainties due to atmospheric variability. HALO-LIDAR will enable new and better evaluations of weather forecasting and climate models through added value data products based on combinations of instruments and careful quantification of errors and uncertainties.

激光雷达对风、水蒸气、臭氧、气溶胶或云的测量是大量计划中的 HALO 任务的关键组成部分。尽管这些任务有不同的科学目标，并使用不同的激光雷达和其他仪器组合，但对温带天气系统的共同关注和对激光雷达数据的共同依赖为开发方法和获得超出单个任务范围的科学结果提供了独特的机会。 HALO-LIDAR 的目标是通过解决跨越多个 HALO 任务的科学目标子集来利用这些协同作用，并开发基于激光雷达和其他仪器的数据组合来分析物理相关量的方法。科学目标围绕测量传输和通量，特别是北大西洋气旋上游发展中的水蒸气、其温暖区域的卷云特性，以及通过成分测量的组合来识别相关的关键物理过程。来自相关项目的模型数据，特别是集合模拟，将被用来量化大气变化引起的不确定性。 HALO-LIDAR 将通过基于仪器组合以及对误差和不确定性的仔细量化的增值数据产品，对天气预报和气候模型进行新的、更好的评估。
