淮河流域滁州水文基地降水观测网小时降水数据集（2019-2022）

该数据集为河海大学雍斌团队通过在淮河流域滁州水文基地布设雨量收集仪器获得的降水观测数据。原始数据采集于HOBO RG3-M雨量计，采集时间为2019年1月到2022年12月。研究组首先通过目视解译法排除异常值，再利用MATLAB软件对数据进行极值检验和时间域检验，最后将数据累加至1hr形成逐小时降水观测数据集。该数据集的收集对卫星降水产品地面格网高精度的验证提供了参考，可较大程度提升卫星降水产品的精度，对未来利用准实时卫星降水产品进行自然灾害事件预警具有重要的意义。

This dataset is a collection of precipitation observation data acquired by the team led by Yong Bin from Hohai University, which was obtained by deploying rainfall monitoring instruments at the Chuzhou Hydrological Base in the Huaihe River Basin. The raw data was collected using HOBO RG3-M rain gauges, with the acquisition period running from January 2019 to December 2022. The research team first excluded outliers through visual interpretation, then performed extreme value tests and time-domain tests on the data using MATLAB software, and finally aggregated the data into 1-hour intervals to create the final hourly precipitation observation dataset. This dataset provides a valuable reference for the high-precision validation of satellite precipitation products using ground-based grid observations, can greatly enhance the accuracy of satellite precipitation products, and is of great importance for future natural disaster early warning applications that utilize quasi-real-time satellite precipitation products.
