  abstract = {{T}he analysis of feedback effects between continental surfaces and the atmosphere is a key element in the understanding of {A}frican monsoon dynamics. {F}or this reason, the monitoring of surface parameters, in particular soil moisture, is essential. {S}atellite remote sensing appears to be the most suitable means of obtaining data relevant to such parameters. {T}he present paper presents the results of statistical analysis of soil moisture products based on data recorded by the {ERS} scatterometer, over the period 1992-2006, from two sites in {N}iger and {M}ali in the {S}ahel climatic region. {S}oil moisture products were validated over these two sites using ground data measurements and {ASAR}/{ENVISAT} estimations. {T}he soil moisture distribution during the monsoon period is described, and the temporal correlation between estimated soil moisture levels is computed. {F}inally, the dynamics of cells corresponding to precipitation events and high surface moisture values were evaluated in the studied regions, thereby revealing variations during the monsoon period as well as site specific trends.},
