作为对雨量计昂贵的操作和维护成本的妥协，我们在世界许多地区面临着雨量计数量的显着下降。如何有效地部署新的或删除现有的雨量计以创建最佳的降雨信息的问题变得越来越重要。另一方面，更大规模的遥感降雨测量，尽管与传统雨量计降雨测量相比质量较差，但可以深入了解当地的风暴特征，这是设计雨量计网络的传统方法所寻求的。基于这些事实，本研究提出了一种利用遥感降雨数据集进行雨量计网络设计的新方法，旨在探讨有多少雨量计是必要的以及它们应该放置在哪里。主成分分析（PCA）用于分析雷达网格网络的冗余度并确定雨量计的数量，同时通过聚类分析（CA）选择来确定潜在位置。所提出的方法已对由天气雷达网格网络测量的 373 个不同风暴事件进行了执行，并与英格兰西南部现有的密集雨量计网络进行了比较。由于结构简单，所提出的方案可以很容易地在其他研究领域实施。本研究为雨量计网络设计提供了新的见解，也是利用遥感数据解决传统雨量计问题的初步尝试。
We have been facing a remarkable decline in the number of raingauges in many areas of the world, as a compromise to the expensive cost of operating and maintaining raingauges. The question of how to effectively deploy new or remove current raingauges in order to create optimal rainfall information is becoming more and more important. On the other hand, larger-scaled remotely-sensed rainfall measurements, although poorer quality compared with traditional raingauge rainfall measurements, provide an insight into the local storm characteristics, which traditional methods for designing a raingauge network sort to seek. Based on these facts, this study proposes a new methodology for raingauge network design using remotely-sensed rainfall data set, which aims to explore how many gauges are essential and where they should be placed. Principal component analysis (PCA) is used to analyse the redundancy of the radar grids network and determine the number of raingauges while the potential locations are determined by cluster analysis (CA) selection. The proposed methodology has been performed on 373 different storm events measured by a weather radar grids network, and compared against an existing dense raingauge network in Southwest England. Due to the simple structure, the proposed scheme could be easily implemented in other study areas. This study provides a new insight into raingauge network design, which is also a preliminary attempt of using remotely-sensed data to solve the traditional raingauge problems.
