A roadmap for calibration and validation
Date:10/22/2007

ctive role in tackling these issues. The CEOS Working Group on Calibration and Validation (WGCV) established consensus within the international community that calibration, validation and quality assurance processes should be incorporated into satellite programmes in a harmonised way.

Through the session discussions, the workshop participants reached a consensus on a roadmap towards the establishment of Cal/Val best practices. These best practices will be issued as CEOS endorsed guidelines under the auspices of GEO for implementation by the agencies and will allow data to have an ascribed quality associated with it. The guidelines will cover all aspects of the data quality from instrument characterisation to engineering calibration and geophysical validation.

Participants identified the need for a Cal/Val specific data policy and the allocation of the necessary resources through coordinated efforts of GEOSS members to allow the efficient implementation of these guidelines. Sufficient resources will be required to ensure the continued end-to-end operation and maintenance of a fully traceable Cal/Val system.

The first step towards harmonisation across the global Earth Observation Cal/Val community is the development of a dedicated CEOS WGCV Cal/Val portal, which will facilitate the implementation of these activities on behalf of GEOSS.
