  abstract = {{D}uring the monsoon season, the spatiotemporal variability of rainfall impacts the growth of vegetation in the {S}ahel. {T}his study evaluates this effect for the {F}erlo basin in central northern {S}enegal. {R}elationships between rainfall, soil moisture ({SM}), and vegetation are assessed using remote sensing data ({TRMM}3{B}42 and {RFE} 2.0 for rainfall, {ESA}-{CCI}.{SM} for soil moisture and {MODIS} {L}eaf {A}rea {I}ndex ({LAI})). {T}he principal objective was to analyze the response of vegetation growth to water availability during the rainy season using statistical criteria at the scale of homogeneous vegetation-soil zones. {T}he study covers the period from {J}une to {S}eptember for the years 2000 to 2010. {T}he surface {SM} is well correlated with both rainfall products. {O}n ferruginous soils, better correlation of intra-seasonal variations and stronger sensitivity of the vegetation to rainfall are found compared to lithosols soils. {LAI} responds, on average, two to three weeks after a rainfall anomaly. {M}oreover, dry spells (negative anomalies) of seven days' length (three days for {SM} anomaly) significantly affect vegetation growth (maximum {LAI} within the season). {A} strong and significant link is also found between total precipitation and the number of dry spells. {T}hese datasets proved to be sufficiently reliable to assess the impacts of rainfall variability on vegetation dynamics.},
