Sea Surface Salinity from French RESearcH Vessels : Delayed mode dataset, annual release

french research vessels have been collecting thermo-salinometer (tsg) data since the early 2000 in contribution to the gosud programme. the set of homogeneous instruments is permanently monitored and regularly calibrated. water samples are taken on a daily basis by the crew and later analysed in the laboratory. we present here the delayed mode processing of the time series intiated in 2001 dataset and an overview of the resulting quality. the careful calibration and instrument maintenance, complemented with a rigorous adjustment on water samples lead to reach an accuracy of a few 10-² pss in salinity or evenless. global comparison with the isas13 argo gridded product shows an excellent agreement of the datasets. the sss-fresh dataset appears as highly valuable for the "calibration and validation" of the new satellite observations delivered by smos, aquarius and smap.

自20世纪早期起，法国研究船只便开始收集温盐计（TSG）数据，为GOSUD计划做出贡献。该套同质仪器设备得到持续监控，并定期进行校准。船员每日采集水样，随后在实验室进行分析。本文档展示了自2001年起启动的时间序列数据的延迟处理模式，并对处理结果的质量进行了概述。精确的校准与仪器维护，辅以对水样的严格调整，使得盐度测量精度达到数个10⁻² PSS，甚至更优。与ISA-S13 Argo网格产品进行的全球比较显示，数据集之间具有卓越的一致性。SSS-Fresh数据集在SMOS、Aquarius和SMAP等新卫星观测数据的“校准与验证”方面展现出极高的价值。
