  abstract = {{I}n this study, 16 satellite-based precipitation products ({SPP}s) comprising satellite, gauge and reanalysis datasets were assessed on a monthly time step using precipitation data from 11 gauge stations across {N}igeria within the 2000-2012 period as reference. {D}espite the ability of some of the {SPP}s to reproduce the salient north-south pattern of the annual rainfall field, the {K}ling-{G}upta efficiency ({KGE}) results revealed substantial discrepancies among the {SPP} estimates. {G}enerally, the {SPP} reliability varies spatially and temporally, with all {SPP}s performing better over part of central {N}igeria during the dry season. {W}hen we compared the real-time and adjusted satellite-based products, the results showed that the adjusted products had a better {KGE} score. {T}he assessment also showed that the reliability of integrated multi-satellite retrievals for {G}lobal {P}recipitation {M}ission ({IMERG}) products was consistent with that of their predecessor {T}ropical {R}ainfall {M}easuring {M}ission ({TRMM}) multi-satellite precipitation analysis ({TMPA}). {F}inally, the best overall scores were obtained from multi-source weighted-ensemble precipitation ({MSWEP}) v.2.2 and {IMERG}-{F} v.6. {B}oth products are therefore suggested for further hydrological studies.},
