  abstract = {{S}tudy region: {M}orocco, {N}orthwestern {A}frica. {S}tudy focus: {S}ince {A}pril 2002, the {G}ravity {R}ecovery and {C}limate {E}xperiment ({GRACE}) mission have opened new pathways for hydrologists to monitor the changes in terrestrial total water storage ({TWS}). {H}ere, the {C}enter for {S}pace {R}esearch ({CSR}), {G}oddard {S}pace {F}light {C}enter ({GSFC}), {J}et {P}ropulsion {L}aboratory ({JPL}), and the average ({AVG}) {GRACE} mascon solutions were used to examine the changes in {TWS} and groundwater storages ({GWS}) in {M}orocco, with an emphasis on natural replenishment events and their link to snow cover area ({SCA}) and rainfall variability. {N}ew hydrological insights for the region: {T}he results showed that {GRACE} {TWS} from {AVG} ({TWSAVG}) and {GSFC} ({TWSGSFC}) can fairly describe the temporal patterns of the groundwater level ({GWL}). {M}oreover, during 2002-2020, the {TWS} underwent a strong depletion relatively masked by natural recharge events. {T}his was revealed as we identified two intermittent depletion episodes with statistically significant rates (-1.03 +/- 0.11 to-0.31 +/- 0.1 cm yr(-1)) higher than those obtained for the long-term trend lines (-0.28 +/- 0.11 to-0.15 +/- 0.07 cm yr(-1)). {T}he {TWS} appeared to be strongly linked with the {SCA} metrics and rainfall indices with 1-3 months of lag. {O}ur findings suggest that the rainfall distribution can be more insightful about changes in groundwater levels compared to the rainfall monthly totals.},
