Abstract: The objective of the Argo project is to obtain temperature and salinity data with the observation precision at least over 0.5℃ and 0.01PSU respectively. Conventionally, the salinity is derived from the conductance of the seawater indirectly, and the sensor to measure the conductance is easy to produce large drift. Therefore, quality control over the Argo data must be carried out. This paper gives a detailed introduction to the procedures of Real-time and Delayed-mode quality control for Argo data.
