Data submitted to the CLIVAR Moored Instrument Data Assembly Centre at BODC go through several steps before they are incorporated in the CLIVAR database. After data are received they are converted to a common format (netCDF) and quality controlled using automated and visual methods. Comprehensive metadata and data documentation are compiled describing the data and any problems encountered to increase the future usability of the data. The aim of quality control is to ensure that the data are of a consistent standard and to guarantee their long-term safeguarding and utilization.
