  abstract = {{T}otal and wetmineral dust deposition has beenmonitored since 2006 at three {S}ahelian stations in {S}enegal, {M}ali, and {N}iger, respectively at the weekly and the event time scale. {A}verage annual deposited mass fluxes range from 75 to 183 gm(-2) yr(-1), from west to east. {D}eposition fluxes exhibit a clear seasonal cycle in {M}ali and {N}iger. {H}igh wet deposition fluxes result from an optimum phasing between dust concentration and precipitation: the maximum occurring at the beginning of the wet season, after the maximum of dust concentration and before the precipitation maximum. {T}he contribution of wet to total deposition varies from 67% in {M}ali to 8% in {S}enegal. {I}t is the main factor of variability of the deposition fluxes from year to year and at the seasonal scale in {N}iger and {M}ali. {W}et deposition fluxes in {M}ali and {N}iger are mainly due to the wash out of dust emitted by convective systems. {I}n {S}enegal, the deposition fluxes are lower and dominated by dry deposition (92% of the annual deposition flux). {T}his is due to the low occurrence of convective systems producing local dust emissions and intense wet deposition. {T}he dry deposition fluxes are primarily driven by the variability of the dust concentration. {T}he dry deposition velocities derived from our measurements are consistent with those estimated by theoretical models. {S}cavenging ratios computed from the measured wet deposition fluxes, dust concentrations, and precipitation are anticorrelated with precipitation amounts. {T}his suggests that most of the atmospheric dust is scavenged at the very beginning of the precipitation events.},
