The　global　sea-level　budget　is　studied　using　the　Gravity　Recovery　and　Climate　Experiment　(GRACE)　solutions,　Satellite　Altimetry　and　Argo　observations　based　on　the　updated　budget　equation.　When　the　global　ocean　mass　change　is　estimated　with　the　updated　Tongji-Grace2018　solution,　the　misclosure　of　the　global　sea-level　budget　can　be　reduced　by　0.11-0.22　mm/year　compared　to　four　other　recent　solutions　(i.e.　CSR　RL06,　GFZ　RL06,　JPL　RL06　and　ITSG-Grace2018)　over　the　period　January　2005　to　December　2016.　When　the　same　missing　months　as　the　GRACE　solution　are　deleted　from　altimetry　and　Argo　data,　the　misclosure　will　be　reduced　by　0.06　mm/year.　Once　retained　the　GRACE　C-20　term,　the　linear　trends　of　Tongji-Grace2018　and　ITSG-Grace2018　solutions　are　2.60　+/-　0.16　and　2.54　+/-　0.16　mm/year,　closer　to　2.60　+/-　0.14　mm/year　from　Altimetry-Argo　than　the　three　RL06　official　solutions.　Therefore,　the　Tongji-Grace2018　solution　can　reduce　the　misclosure　between　altimetry,　Argo　and　GRACE　data,　regardless　of　whether　the　C-20　term　is　replaced　or　not,　since　the　low-degree　spherical　harmonic　coefficients　of　the　Tongji-Grace2018　solution　can　capture　more　ocean　signals,　which　are　confirmed　by　the　statistical　results　of　the　time　series　of　global　mean　ocean　mass　change　derived　from　five　GRACE　solutions　with　the　spherical　harmonic　coefficients　truncated　to　different　degrees　and　orders.
