Quality Control, Quality Assurance, and Quality Flags [Presentation at QARTOD III, 2-4 November 2005].

Abstract

The distinction between quality control and quality assurance is presented, with activity examples of each listed. A review of data flagging recommendations is provided, from the first QARTOD workshop and from three breakout groups during the second QARTOD workshops. To foster discussions towards identifying a standard, existing U.S. and international program-specific data flagging schemes are reviewed.
