  abstract = {{T}he {A}rctic freshwater budget is critical for understanding the climate in the northern regions. {H}owever, the hydrology of the {A}rctic circumpolar tundra region ({ACTR}) and the largest pan-{A}rctic rivers are still not well understood. {I}n this paper, we analyze the spatiotemporal variations in the terrestrial water storage ({TWS}) of the {ACTR} and three of the largest pan-{A}rctic river basins ({L}ena, {M}ackenzie, {Y}ukon). {T}o do this, we utilize monthly {G}ravity {R}ecovery and {C}limate {E}xperiment ({GRACE}) data from 2002 to 2016. {T}ogether with global land reanalysis, and river runoff data, we identify declining {TWS} trends throughout the {ACTR} that we attribute largely to increasing evapotranspiration driven by increasing summer air temperatures. {I}n terms of regional changes, large and significant negative trends in {TWS} are observed mainly over the {N}orth {A}merican continent. {A}t basin scale, we show that, in the {L}ena {R}iver basin, the autumnal {TWS} signal persists until the spring of the following year, while in the {M}ackenzie {R}iver basin, the {TWS} level in the autumn and winter has no significant impact on the following year. {A}s expected global warming is expected to be particularly significant in the northern regions, our results are important for understanding future {TWS} trends, with possible further decline.},
