  abstract = {{T}he total water storage change ({TWSC}) over land is a major component of the global water cycle, with a large influence on the climate variability, sea level budget and water resource availability for human life. {I}ts first estimates at a large scale were made available with {GRACE} ({G}ravity {R}ecovery and {C}limate {E}xperiment) observations for the 2002-2016 period, followed since 2018 by the launch of the {GRACE}-{FO} ({F}ollow-{O}n) mission. {I}n this paper, using an approach based on the water mass conservation rule, we propose to merge satellite-based observations of precipitation and evapotranspiration with in situ river discharge measurements to estimate {TWSC} over longer time periods (typically from 1980 to 2016), compatible with climate studies. {W}e performed this task over five major {A}sian basins, subject to both large climate variability and strong anthropogenic pressure for water resources and for which long-term records of in situ discharge measurements are available. {O}ur {S}atellite {W}ater {C}ycle ({SAWC}) reconstruction provides {TWSC} estimates very coherent in terms of seasonal and interannual variations with independent sources of information such as (1) {TWSC} {GRACE}-derived observations (over the 2002-2015 period), (2) {ISBA}-{CTRIP} ({I}nteractions between {S}oil, {B}iosphere and {A}tmosphere {CNRM} - {C}entre {N}ational de {R}echerches {M}eteorologiques - {T}otal {R}unoff {I}ntegrating {P}athways) model simulations (1980-2015) and (3) the multi-satellite inundation extent (1993-2007). {T}his analysis shows the advantages of the use of multiple satellite-derived datasets along with in situ data to perform a hydro- logically coherent reconstruction of a missing water component estimate. {I}t provides a new critical source of information for the long-term monitoring of {TWSC} and to better understand its critical role in the global and terrestrial water cycle.},
