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.
