Donner, Darren Ghent, Alexander Gruber, Thomas Kaminski, Julian Kinzel, Christian Klepp, Jean-Christopher Lambert, Gabriela Schaepman-Strub, Marc Schröder, Tijl VerhoelstAssessing the inherent uncertainties in satellite data products is a challenging task. Different technical approaches have been developed in the Earth Observation (EO) communities to address the validation problem which results in a large variety of methods as well as terminology. This paper reviews state-of-the-art methods of satellite validation and documents their similarities and differences. First, the overall validation objectives and terminologies are specified, followed by a generic mathematical formulation of the validation problem. Metrics currently used as well as more advanced EO validation approaches are introduced thereafter. An outlook on the applicability and requirements of current EO validation approaches and targets is given.
