  abstract = {{P}recipitation forcing is usually the main source of uncertainty in hydrology. {I}t is of crucial importance to use accurate forcing in order to obtain a good distribution of the water throughout the basin. {F}or real-time applications, satellite observations allow quasi-real-time precipitation monitoring like the products {PERSIANN} ({P}recipitation {E}stimation from {R}emotely {S}ensed {I}nformation using {A}rtificial {N}eural {N}etworks, {TRMM} ({T}ropical {R}ainfall {M}easuring {M}ission) or {CMORPH} ({CPC} ({C}limate {P}rediction {C}enter) {MORPH}ing). {H}owever, especially in {W}est {A}frica, these precipitation satellite products are highly inaccurate and the water amount can vary by a factor of 2. {A} post-adjusted version of these products exists but is available with a 2 to 3 month delay, which is not suitable for real-time hydrologic applications. {T}he purpose of this work is to show the possible synergy between quasi-real-time satellite precipitation and soil moisture by assimilating the latter into a hydrological model. {S}oil {M}oisture {O}cean {S}alinity ({SMOS}) soil moisture is assimilated into the {D}istributed {H}ydrology {S}oil {V}egetation {M}odel ({DHSVM}) model. {B}y adjusting the soil water content, water table depth and streamflow simulations are much improved compared to real-time precipitation without assimilation: soil moisture bias is decreased even at deeper soil layers, correlation of the water table depth is improved from 0.09-0.70 to 0.82-0.87, and the {N}ash coefficients of the streamflow go from negative to positive. {O}verall, the statistics tend to get closer to those from the reanalyzed precipitation. {S}oil moisture assimilation represents a fair alternative to reanalyzed rainfall products, which can take several months before being available, which could lead to a better management of available water resources and extreme events.},
