Ocean Data Standards Volume 3. Recommendation for a Quality Flag Scheme for the Exchange of Oceanographic and Marine Meteorological Data. Version 1.

Abstract

...This document describes a two-level quality flag scheme (QF) that will facilitate the exchange and integration of multi-disciplinary oceanographic and marine meteorological data. The first, or primary, level defines the data quality flags only, while the secondary level complements the first level by providing the justification for the quality flags, based on quality control tests or data processing history.
