The provision of a Data Integrity Facility (DIF) within the UK Climate and Environmental Monitoring from Space (CEMS) facility is seen as a unique and innovative differentiator between this and other EO data archive and processing centres. As such, the UK Technology Strategy Board (TSB) is supporting the prototyping of a DIF within the CEMS environment, using data from the Advanced Along-Track Scanning Radiometer (AATSR) as a case study. This paper outlines the definition of EO data integrity being adopted by the project team, the associated metadata to be populated by the system, the capabilities and functions of the system itself and the project’s approach to ensuring compliance to the QA4EO initiative.
