Investigation of the influence of new active remote sensing instruments on numerical weather prediction models

在最近的国际野外活动中，DLR在长时间飞行中进行了高分辨率水蒸气和风场的激光雷达测量。在这个项目中，这些数据将被处理、分析并准备用于数值模拟。在第一阶段，将结合资料和数值模拟进行个案研究，以描述对流层中对流边界层和对流层上层的水蒸气分布。制定了如何利用激光雷达对水汽和风的观测来改进定量降水预报的策略。在第二阶段（第3年以上），将在优先项目“QPF”的现场阶段进行目标激光雷达测量。

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".
