The EO4FLOOD project (https://eo4flood.org/) aims to demonstrate the maturity and effectiveness of cutting-edge satellite observations for enhancing flood forecasting systems. By leveraging advanced satellite technologies and state-of-the-art algorithms, the project improves the accuracy and timeliness of hydrological and hydraulic models, leading to more reliable and precise flood predictions. This repository provides the Advanced Open Earth Observation Dataset (EO4FLOOD dataset), built from the latest products of both ESA and non-ESA satellite missions. The dataset includes nine basins with high spatial and temporal resolution satellite data and is designed to support research and operational applications in flood monitoring and forecasting. A comprehensive description of the dataset, including its processing workflow, methodological framework, and technical specifications, is provided in the official project documentation, ATBD and PSD. These documents will be made available on the project website, allowing users to verify the dataset structure, assumptions, and implementation details directly from the project materials.
