  abstract = {{L}aunched in 2014, the {G}lobal {P}recipitation {M}easurement ({GPM}) mission aimed at ensuring the continuity with the {T}ropical {R}ainfall {M}easuring {M}ission ({TRMM}) launched in 1997 that has provided unprecedented accuracy in {S}atellite {P}recipitation {E}stimates ({SPE}s) on the near-global scale. {S}ince then, various {SPE} versions have been successively made available from the {GPM} mission. {T}he present study assesses the potential benefits of the successive {GPM} based {SPE}s product versions that include the {I}ntegrated {M}ulti-{S}atellite {R}etrievals for {GPM} ({IMERG}) version 3 to 5 (-v03, -v04, -v05) and the {G}lobal {S}atellite {M}apping of {P}recipitation ({GSM}a{P}) version 6 to 7 (-v06, -v07). {A}dditionally, the most effective {TRMM} based {SPE}s products are also considered to provide a first insight into the {GPM} effectiveness in ensuring {TRMM} continuity. {T}he analysis is conducted over different geomorphic and meteorological regions of {P}akistan while using 88 precipitations gauges as the reference. {R}esults show a clear enhancement in precipitation estimates that were derived from the very last {IMERG}-v05 in comparison to its two previous versions {IMERG}-v03 and -v04. {I}nterestingly, based on the considered statistical metrics, {IMERG}-v03 provides more consistent precipitation estimate than {IMERG}-v04, which should be considered as a transition {IMERG} version. {A}s expected, {GSM}a{P}-v07 precipitation estimates are more accurate than the previous {GSM}a{P}-v06. {H}owever, the enhancement from the old to the new version is very low. {M}ore generally, the transition from {TRMM} to {GPM} is successful with an overall better performance of {GPM} based {SPE}s than {TRMM} ones. {F}inally, all of the considered {SPE}s have presented a strong spatial variability in terms of accuracy with none of them outperforming the others, for all of the gauges locations over the considered regions.},
