Quality Control
One of the unique and most important aspects of GODAE is the characterization of the errors and uncertainties in the outputs – both, data and forecasts. This is a fundamental component of any ocean data assimilation system. It is likely that decisions made at the quality control step can affect the success or failure of the entire system. Accepting erroneous data can cause an incorrect analysis, while rejecting extreme data can miss important events and anomalous features.
An integrated, end-to-end system should ensure that the results of the quality control procedures are recorded for independent analysis and later use. If the quality control is carried out well, then it can reduce the duplication of effort among the chain of users of the ocean data - value added is not lost or misinterpreted.
As GODAE develops a range of operational complex ocean analysis and prediction systems, it is important that improved procedures be developed for routinely assessing the effectiveness of quality control and for routinely exchanging statistics from the quality control process. The GODAE Intercomparison/metrics group addresses this challenge by developing appropriate standards for intercomparisons.
