  <dc:description>黄河中上游是受气候变化影响的敏感地区，也是我国生态保护的重点地区。极端降水事件导致该地区频繁发生洪水和干旱灾害。极端降水数据集的研发对于保障区域生态安全和防灾减灾具有重要意义。本文基于 1961 年至 2020 年气象站的逐日降水观测数据。经过资料筛选、质量检测和异常值去除，选择并计算了 10 个极端降水指数。通过时间和区域统计得到黄河中上游极端降水指数数据集。经过时间序列和空间模式的质量控制和数据验证，包括单位转换、缺失数据位点的去除和缺失值的插值，数据集具有较高的准确率和可靠性。该数据集可用于分析黄河中上游极端降水事件的时空特征及其对气候变化的响应。它还可以为评估该地区的水资源安全和干旱/洪水灾害风险提供基础数据支持。</dc:description>
