"There are a wide variety of applications for and users of real-time oceanographic data. The quality of those data is dependent upon many factors, including the ability to apply QC flags to real-time data streams. This QC flag manual has been compiled considering multiple QC flagging schemes that have been documented by various sources. The flagging standard suggested in early QARTOD manuals nearly matched the 'Primary Level' scheme presented in IOC 54:V3. Therefore, U.S. IOOS/QARTOD has accepted the IOC 54:V3 scheme as its data QC flag protocol"--Summary.
