The Irrigation+ project aims at advancing Earth Observation (EO) capabilities towards a quantitative, accurate and routine estimation of irrigation information by means of multi-mission satellite EO approaches, especially capitalizing on the latest advances in EO and the advent of the Sentinel missions in synergy with other data types and models. Irrigation+ will be implemented on five experimental sites and will use different retrieval algorithms of the most important variables related to irrigation as well as satellite-based detection and quantification methods to retrieve irrigation volumes. From the results of the experimental analysis, the best algorithms and approaches will be selected and implemented on a regional and global scale. The impact of the produced dataset will be assessed in several science cases and demonstration cases.
