This project aims to advance towards the development of ET estimates at global and regional scales, having as main objectives to develop a Reference Input Data Set to derive and validate ET estimates, and to perform a cross-comparison, error characterization, and validation exercise of a group of selected ET algorithms driven by the Reference Input Data Set. The structure of the proposed study will closely follow the Statement of Work. The work to be carried out will be organized in Work Packages (WP), each representing one of the main tasks. The work will be carried out during three phases. The study is organized in work packages, as shown in the following organigram.
