This Manual has been produced within the context of the Global Temperature-Salinity Pilot Project (GTSPP). Because the work- of assuring the quality of data handled by the Project is shared amongst data centres, it is important to have both consistent and well documented procedures. This Manual describes the means by which data quality is assessed and the actions taken as a result of the procedures. The GTSPP handles all temperature and salinity profile data. This includes observations collected using water samplers, continuous profiling instruments such as CTDs, thermistor chain data and observations acquired using thermosalinographs. These data will reach data processing centres of the Project through the real-time channels of the IGOSS program or in delayed mode through the IODE system. The procedures described here are intended to cover only the above-mentioned data types and specifically for data sent through the IGOSS system. However, there are obvious generalizations that can be.....
