In the frame of this workshop two dedicated working groups have been established, namely the

1. Satellite & In Situ Salinity (SISS) Working Group (WG):

Understanding Stratification and Sub-Footprint Processes

Co-Chairs: J. Boutin (LOCEAN/CNRS), Yi Chao (RSSI), C.Banks (NOC)
Contact: To join this working group please contact Jaqueline Boutin at or Yi Chao at; A common working group mailing list and webpage/webforum, including document sharing and data links is planned.

Scope: The major goal of this WG is to improve our understanding of the link between L-band satellite remotely sensed sea surface salinity (SSS), as provided by SMOS and Aquarius at approximately 1 cm below the sea surface, and in-situ measured salinity, routinely measured at a few meters’ depth by ships and ARGO floats and recently accessible up to a few cm depth by new profilers, surface drifters etc. and to develop methodologies for relating satellite derived salinity to other estimates of sea surface salinity.

2. Working group on salinity inter-comparison/cross-calibration

Co-Chairs: David LeVine (NASA), Gary Lagerloef (ESR), Yann Kerr (CESBIO), JordiFont (ICM/CSIC), M.Portabella (UTM-CSIC)
Contact: To join this working group please contact David LeVine at, who will form a working group mailing list and begin an email "conversation“.

Scope: The focus of this working group is on identifying an approach for inter-comparison/cross-calibration of SMOS and AQUARIUS data. This will include an agreement on the techniques and reference sites being used for this purpose. Before entering the actual inter-comparison, some fundamental issues in the understanding of L-Band remote sensing need to be addressed, specific to both instruments. In the long run this working group aims toward a merged and validated data product using commonly agreed standards. It will need to be confirmed on what level of data the merged product should occur, i.e. level 1 brightness temperatures  (i.e. Fundamental Climate Data Records) or level 2 sea surface salinity (i.e. Thematic Climate Data Records).
