Quality Assurance Issues

Scientific quality assurance is an important part of WP3. With the CDB, it is possible to create diagnostics that use and combine high frequency and high resolution data efficiently. CDB thus makes it relatively easy to verify the scientific quality of a vast array of data in the archive.

Already, during the beta testing phase, data quality issues were observed. Most data in the archive have been converted to ESG conventions and it is only when the data was combined in high level diagnostics that problems arose. With the suite of diagnostics to be included in the CDB, it will be possible to monitor these problems and thus potentially improve the scientific quality of the archive. The initial version of the CDB does not describe a method to report the data quality issues encountered when processing the climate diagnostics but it is expected that in future versions, a reporting mechanism will be implemented.
