  abstract = {{P}ast variations of the recharge is estimated in the {A}tlas {M}ountains, the main recharge area of the {C}ontinental {I}ntercalaire ({CI}) aquifer, one of the major {S}aharan aquifers, over the last 775 kyr. {I}n this {M}editerranean climatic context, continental archives generally record single humid events, grouped in hypothetical time interval and do not offer continuous chronicles of precipitation. {W}e propose to use spatially distributed {C}l-36/{C}l data as a temporal constraint, to infer the past recharge in the {A}tlas area. {B}ased on a simplified but robust climatic scenario, assuming a piston model, we apply a {M}arkov {C}hain {M}onte {C}arlo ({MCMC}) inversion approach to attribute a specific recharge to the last nine interglacial periods and an undifferentiated recharge to the glacial periods. {T}he interglacial recharge values vary from a few mm yr (1) to more than 60 mm yr (1). {G}lacial recharge is less than 1 mm yr (1) . {T}hese values are then analyzed in terms of intensity and allow questioning some initial hypothesis, especially the generally accepted value of the initial {C}l-36/{C}l value (around 133 x 10(-15) at at(-1)). {O}ur analysis suggests a higher value, around 175 x 10(-15) at at(-1). {T}his approach allows us to bring out paleoclimatic information retained in these continental archives. {E}specially, computed recharges provide reliable evidence that {M}arine {I}sotope {S}tage ({MIS}) 5 was more humid than the {H}olocene period in agreement with marine archives that document wet condition in the {N}orth {S}ahara during that period.},
