Luca Brocca, researcher of IRPI-CNR, is coauthor of a paper published on the High Impact journal Reviews on Geophysics (IF 12.3): “Validation practices for satellite based earth observation data across communities”.
The paper reviews state-of-the-art methods of satellite validation across different scientific communities 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. An outlook on the applicability and requirements of current Earth Observation validation approaches and targets is given.
The paper would serve as a reference for the future studies addressed to the validation of satellite observations.
