Hamburg Local Area Weather Radars

Knowledge of small-scale rainfall variability is needed for several meteorological and hydrological applications. For this purpose, the University of Hamburg operates two local area weather radars (LAWR) and five micro rain radars (MRR) in the area of Hamburg. The low-cost, operational, single-polarized X-band weather radars provide measurements with high temporal (30 s), range (60 m), and sampling (1°) resolution within the 20 km scan radius. Studies on short time periods (several months) proofs the performance of this low-cost local area weather radar. For example, a case study on a tornado in a rain event demonstrates its refined resolution compared to the German nationwide C-band radars. A similar observational network of LAWRs and MRRs was deployed in an rural area and proofed its performance in the past. This project covers data sets related to these radar measurements.

对小尺度降雨变率的认知对于众多气象与水文应用至关重要。为此，汉堡大学在汉堡地区运营了两部局部区域天气雷达（LAWR）和五部微型雨雷达（MRR）。这些低成本、实用、单极化的X波段天气雷达能够提供高时间分辨率（30秒）、距离分辨率（60米）和采样分辨率（1°）的测量数据，覆盖20公里的扫描半径。针对短期（数月）的研究证实了这种低成本局部区域天气雷达的性能。例如，关于一场雨事件中龙卷风的研究案例展示了其相较于德国全国范围内的C波段雷达所具有的精细分辨率。在乡村地区部署了类似的观测网络（LAWR和MRR），并在过去证明了其性能。本项目涵盖了与这些雷达测量相关的数据集。
