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 1900s. All the rainfall measurements included in the database are expressed in mm, while the positions of all the rain gauges are converted in the Universal Transverse Mercator coordinate system (WGS 84 UTM 32 N - EPSG 32632). 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境内超过5000个雨量站自20世纪早期起的观测数据，涵盖1、3、6、12及24小时连续时段的年最大降雨量。数据库内所有降雨量观测值均以毫米（mm）为单位，所有雨量站的位置均已转换为通用横轴墨卡托（Universal Transverse Mercator，UTM）坐标系（WGS 84 UTM 32 N - EPSG 32632）。在构建该数据库的过程中，已针对数据一致性、冗余性、记录补全以及系统性地理校验开展了高级数据质量控制工作。
