Abstract The MADIA daily gridded dataset provides the series of the main agro-meteorological variables derived from ERA5 hourly surface data, with a spatial resolution of 0.25 degrees, across the Italian domain for the period 1981-2022. The dataset contains time series of minimum, average and maximum air temperature, minimum and maximum air relative humidity, wind speed, solar radiation, precipitation and reference evapotranspiration according to the FAO Penman-Monteith method. Data is provided at daily temporal resolution and in csv format (every cell is identified by the latitude/longitude coordinates of its centre). The dataset is annotated with discovery and description metadata. A vector file is included with the ERA5 cell polygons covering the Italian country for visualizing and mapping csv data. In order to facilitate the data reuse for computing statistics at Italian NUTS 2 and 3 levels, a complementary vector file which reports the cell weight in terms of fraction covered of each administrative unit considered, as well as its altitude, is provided in: Parisse Barbara, Alilla Roberta, Pepe Antonio Gerardo, & De Natale Flora.

This version (v.1.2) the MADIA daily dataset replaces the previous one (v.1.1) to update the erroneously empty 2022_e5_d.csv file.
