Lidar measurements of highly resolved water vapour and wind fields have been performed by DLR along extended flights in recent international field campaigns. In this project, these data will be processed, analysed and prepared for use in numerical simulations. In the first phase, selected case studies combining the data and numerical simulations will be performed to characterise the tropospheric water vapour distribution in the convective boundary layer and in the upper troposphere. Strategies are developed how lidar observations of water vapour and wind can be utilised to improve the quantitative precipitation forecast. In the second phase (years 3+) targeted lidar measurements will be performed in the field phase of the priority programme "QPF".

在最近的国际实地活动中，德国航天中心沿着进行了长时间飞行，利用激光雷达对高分辨率的水蒸气和风场进行了测量。在本项目中，将对这些数据进行处理、分析和准备，以便用于数值模拟。在第一阶段，将结合数据和数值模拟进行选定的个案研究，以确定对流边界层和对流层上层的对流层水汽分布。制定战略如何激光雷达观测的水蒸气和风可以用来提高定量降水预报。在第二阶段（3年以上），将在优先方案“QPF”的实地阶段进行有针对性的激光雷达测量。
