European Long-term Irrigation Area Datasets version 1.0

These files accompany the manuscript titled "Climate-Driven Interannual Variability in Subnational Irrigation Areas Across Europe" in the journal Communications Earth & Environment.

We have developed the European Long-term Irrigation Area Dataset (ELIAD), which offers annual subnational data on total irrigated and irrigable areas for 32 European regions from 1990 to 2020. For most countries, the data is at the NUTS2 level, except for the UK, Germany, and Ireland, where it is at the NUTS1 level.

Supplementary A: Contains the supplementary figures and tables referenced in the manuscript.Supplementary B: Provides detailed information on the irrigation reference periods for EU farm structure surveys and agricultural censuses.Supplementary C: Describes the methodology used to generate the ELIAD dataset.Supplementary D: Includes the ELIAD dataset itself.Supplementary E: Details the remote sensing products used for comparison with ELIAD in the manuscript.Supplementary F: Contains the data directly used in the figures and tables presented in the manuscript.
