Improved Italian - Rainfall Extreme Dataset (I2-RED)

The I²-RED (Improved I-RED) database includes the annual maximum rainfall depths in 1, 3, 6, 12 and 24 consecutive hours from more than 5000 rain gauge stations across Italy, recorded starting from the early 1900. All the rainfall measurements included in the database are expressed in mm, while the positions of all the rain gauges are converted in WGS 84 UTM 32 N - EPSG 32632 reference system. An advanced data quality control in terms of consistency, redundancy, gap-filling of records and systematic geographical checks has been carried out while creating I²-RED.I²-RED（Improved I-RED）数据库收录了意大利全境超5000个雨量站的观测资料，包含连续1、3、6、12及24小时时段的年最大降雨深度，其观测记录始于20世纪初。该数据库内所有降雨测量值均以毫米（mm）为单位，所有雨量站的空间坐标均统一转换至WGS 84 UTM 32 N - EPSG 32632参考坐标系。在构建I²-RED数据库的过程中，研究团队已围绕数据一致性、冗余性校验、记录缺失补全及系统性地理核查等维度，开展了先进的数据质量控制工作。
