  abstract = {{T}he tropical {I}ndian {O}cean experiences an interannual mode of climatic variability, known as the {I}ndian {O}cean {D}ipole ({IOD}). {T}he signature of this variability in ocean salinity is hypothesized based on modeling and assimilation studies, on account of scanty observations. {S}oil {M}oisture and {O}cean {S}alinity ({SMOS}) satellite has been designed to take up the challenge of sea surface salinity remote sensing. {W}e show that {SMOS} data can be used to infer the pattern of salinity variability linked with the {IOD} events. {T}he core of maximum variability is located in the central tropical basin, south of the equator. {T}his region is anomalously salty during the 2010 negative {IOD} event, and anomalously fresh during the 2011 positive {IOD} event. {T}he peak-to-peak anomaly exceeds one salinity unit, between late 2010 and late 2011. {I}n conjunction with other observational datasets, {SMOS} data allow us to draw the salt budget of the area. {I}t turns out that the horizontal advection is the main driver of salinity anomalies. {T}his finding is confirmed by the analysis of the outputs of a numerical model. {T}his study shows that the advent of {SMOS} makes it feasible the quantitative assessment of the mechanisms of ocean surface salinity variability in the tropical basins, at interannual timescales.},
