Delayed Mode Data
The delayed mode data are made available for two different periods, before and after 2002/2003, having different quality control procedures and data format.
Reports or Publications using data from this web page should acknowledge the origin of the data. The suggested sentence is: "Sea surface salinity data derived from thermosalinograph instruments installed onboard voluntary observing ships were collected, validated, archived, and made freely available by the French Sea Surface Salinity Observation Service (http://www.legos.obs-mip.fr/observations/sss/)".
