Understanding　sea　level　change　is　of　paramount　importance,it　indirectly　reflects　the　changes　of　climate-related　factors　in　earth　system.Based　on　a　set　of　sea　level　fingerprints　and　steric　empirical　orthogonal　functions,a　joint　inversion　is　applied　by　combining　time-varying　gravity　data　and　satellite　altimetry　data　to　derive　global　sea　level　change　from　April　2002　to　February　2020.In　this　research,global　sea　level　change　was　divided　into　the　contributions　of　polar　ice　sheets　melting,terrestrial　glaciers　melting,terrestrial　water　storage　change,glacial　isostatic　adjustment　and　steric　effect.Joint　inversion　result　shows　that　global　mean　steric　sea　level　change　is　1.08±0.05　mm/a,which　is　consistent　with　the　results　of　relevant　literature.It　was　found　that　the　joint　inversion　which　combined　altimetry　and　time-varying　gravity　data　could　reduce　the　underestimation　of　global　mean　ocean　mass　change　during　GRACE　Follow-On　period.Regional　sea　level　changes　were　investigated　by　joint　inversion,in　most　coastal　areas,inversion　results　are　good　of　quality,which　shows　that　this　method　can　be　used　to　study　regional　sea　level　change.　©　2022　SinoMaps　Press.　All　rights　reserved.
